DESCRIPTION
       You can query/set/replace/unset options with this command. The name is actually the
       section and the key separated by a dot, and the value will be escaped.

       Multiple lines can be added to an option by using the --add option. If you want to update
       or unset an option which can occur on multiple lines, a POSIX regexp value_regex needs to
       be given. Only the existing values that match the regexp are updated or unset. If you want
       to handle the lines that do not match the regex, just prepend a single exclamation mark in
       front (see also the section called "EXAMPLES").

       The type specifier can be either --int or --bool, to make git config ensure that the
       variable(s) are of the given type and convert the value to the canonical form (simple
       decimal number for int, a "true" or "false" string for bool), or --path, which does some
       path expansion (see --path below). If no type specifier is passed, no checks or
       transformations are performed on the value.

       When reading, the values are read from the system, global and repository local
       configuration files by default, and options --system, --global, --local and --file
       <filename> can be used to tell the command to read from only that location (see the
       section called "FILES").

       When writing, the new value is written to the repository local configuration file by
       default, and options --system, --global, --file <filename> can be used to tell the command
       to write to that location (you can say --local but that is the default).

       This command will fail with non-zero status upon error. Some exit codes are:

	1. The config file is invalid (ret=3),

	2. can not write to the config file (ret=4),

	3. no section or name was provided (ret=2),

	4. the section or key is invalid (ret=1),

	5. you try to unset an option which does not exist (ret=5),

	6. you try to unset/set an option for which multiple lines match (ret=5), or

	7. you try to use an invalid regexp (ret=6).

       On success, the command returns the exit code 0.

OPTIONS
       --replace-all
	   Default behavior is to replace at most one line. This replaces all lines matching the
	   key (and optionally the value_regex).

       --add
	   Adds a new line to the option without altering any existing values. This is the same
	   as providing ^$ as the value_regex in --replace-all.

       --get
	   Get the value for a given key (optionally filtered by a regex matching the value).
	   Returns error code 1 if the key was not found and error code 2 if multiple key values
	   were found.

       --get-all
	   Like get, but does not fail if the number of values for the key is not exactly one.

       --get-regexp
	   Like --get-all, but interprets the name as a regular expression and writes out the key
	   names. Regular expression matching is currently case-sensitive and done against a
	   canonicalized version of the key in which section and variable names are lowercased,
	   but subsection names are not.

       --global
	   For writing options: write to global /.gitconfig file rather than the repository
	   .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and
	   the/.gitconfig file doesn't.

	   For reading options: read only from global ~/.gitconfig and from
	   $XDG_CONFIG_HOME/git/config rather than from all available files.

	   See also the section called "FILES".

       --system
	   For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the
	   repository .git/config.

	   For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than
	   from all available files.

	   See also the section called "FILES".

       -f config-file, --file config-file
	   Use the given config file instead of the one specified by GIT_CONFIG.

       --remove-section
	   Remove the given section from the configuration file.

       --rename-section
	   Rename the given section to a new name.

       --unset
	   Remove the line matching the key from config file.

       --unset-all
	   Remove all lines matching the key from config file.

       -l, --list
	   List all variables set in config file.

       --bool
	   git config will ensure that the output is "true" or "false"

       --int
	   git config will ensure that the output is a simple decimal number. An optional value
	   suffix of k, m, or g in the config file will cause the value to be multiplied by 1024,
	   1048576, or 1073741824 prior to output.

       --bool-or-int
	   git config will ensure that the output matches the format of either --bool or --int,
	   as described above.

       --path
	   git-config will expand leading ~ to the value of $HOME, and ~user to the home
	   directory for the specified user. This option has no effect when setting the value
	   (but you can use git config bla ~/ from the command line to let your shell do the
	   expansion).

       -z, --null
	   For all options that output values and/or keys, always end values with the null
	   character (instead of a newline). Use newline instead as a delimiter between key and
	   value. This allows for secure parsing of the output without getting confused e.g. by
	   values that contain line breaks.

       --get-colorbool name [stdout-is-tty]
	   Find the color setting for name (e.g.  color.diff) and output "true" or "false".
	   stdout-is-tty should be either "true" or "false", and is taken into account when
	   configuration says "auto". If stdout-is-tty is missing, then checks the standard
	   output of the command itself, and exits with status 0 if color is to be used, or exits
	   with status 1 otherwise. When the color setting for name is undefined, the command
	   uses color.ui as fallback.

       --get-color name [default]
	   Find the color configured for name (e.g.  color.diff.new) and output it as the ANSI
	   color escape sequence to the standard output. The optional default parameter is used
	   instead, if there is no color configured for name.

       -e, --edit
	   Opens an editor to modify the specified config file; either --system, --global, or
	   repository (default).

       --[no-]includes
	   Respect include.*  directives in config files when looking up values. Defaults to on.

FILES
       If not set explicitly with --file, there are four files where git config will search for
       configuration options:

       $GIT_DIR/config
	   Repository specific configuration file.

       ~/.gitconfig
	   User-specific configuration file. Also called "global" configuration file.

       $XDG_CONFIG_HOME/git/config
	   Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty,
	   $HOME/.config/git/config will be used. Any single-valued variable set in this file
	   will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create
	   this file if you sometimes use older versions of Git, as support for this file was
	   added fairly recently.

       $(prefix)/etc/gitconfig
	   System-wide configuration file.

       If no further options are given, all reading options will read all of these files that are
       available. If the global or the system-wide configuration file are not available they will
       be ignored. If the repository configuration file is not available or readable, git config
       will exit with a non-zero error code. However, in neither case will an error message be
       issued.

       All writing options will per default write to the repository specific configuration file.
       Note that this also affects options like --replace-all and --unset. git config will only
       ever change one file at a time.

       You can override these rules either by command line options or by environment variables.
       The --global and the --system options will limit the file used to the global or
       system-wide file respectively. The GIT_CONFIG environment variable has a similar effect,
       but you can specify any filename you want.

ENVIRONMENT
       GIT_CONFIG
	   Take the configuration from the given file instead of .git/config. Using the
	   "--global" option forces this to ~/.gitconfig. Using the "--system" option forces this
	   to $(prefix)/etc/gitconfig.

       GIT_CONFIG_NOSYSTEM
	   Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file.
	   See git(1) for details.

       See also the section called "FILES".

EXAMPLES
       Given a .git/config like this:

	   #
	   # This is the config file, and
	   # a '#' or ';' character indicates
	   # a comment
	   #

	   ; core variables
	   [core]
		   ; Don't trust file modes
		   filemode = false

	   ; Our diff algorithm
	   [diff]
		   external = /usr/local/bin/diff-wrapper
		   renames = true

	   ; Proxy settings
	   [core]
		   gitproxy=proxy-command for kernel.org
		   gitproxy=default-proxy ; for all the rest

       you can set the filemode to true with

	   % git config core.filemode true

       The hypothetical proxy command entries actually have a postfix to discern what URL they
       apply to. Here is how to change the entry for kernel.org to "ssh".

	   % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

       This makes sure that only the key/value pair for kernel.org is replaced.

       To delete the entry for renames, do

	   % git config --unset diff.renames

       If you want to delete an entry for a multivar (like core.gitproxy above), you have to
       provide a regex matching the value of exactly one line.

       To query the value for a given key, do

	   % git config --get core.filemode

       or

	   % git config core.filemode

       or, to query a multivar:

	   % git config --get core.gitproxy "for kernel.org$"

       If you want to know all the values for a multivar, do:

	   % git config --get-all core.gitproxy

       If you like to live dangerously, you can replace all core.gitproxy by a new one with

	   % git config --replace-all core.gitproxy ssh

       However, if you really only want to replace the line for the default proxy, i.e. the one
       without a "for ..." postfix, do something like this:

	   % git config core.gitproxy ssh '! for '

       To actually match only values with an exclamation mark, you have to

	   % git config section.key value '[!]'

       To add a new proxy, without altering any of the existing ones, use

	   % git config --add core.gitproxy '"proxy-command" for example.com'

       An example to use customized color from the configuration in your script:

	   #!/bin/sh
	   WS=$(git config --get-color color.diff.whitespace "blue reverse")
	   RESET=$(git config --get-color "" "reset")
	   echo "${WS}your whitespace color or blue reverse${RESET}"

CONFIGURATION FILE
       The Git configuration file contains a number of variables that affect the Git commands'
       behavior. The .git/config file in each repository is used to store the configuration for
       that repository, and $HOME/.gitconfig is used to store a per-user configuration as
       fallback values for the .git/config file. The file /etc/gitconfig can be used to store a
       system-wide default configuration.

       The configuration variables are used by both the Git plumbing and the porcelains. The
       variables are divided into sections, wherein the fully qualified variable name of the
       variable itself is the last dot-separated segment and the section name is everything
       before the last dot. The variable names are case-insensitive, allow only alphanumeric
       characters and -, and must start with an alphabetic character. Some variables may appear
       multiple times.

   Syntax
       The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ;
       characters begin comments to the end of line, blank lines are ignored.

       The file consists of sections and variables. A section begins with the name of the section
       in square brackets and continues until the next section begins. Section names are not case
       sensitive. Only alphanumeric characters, - and . are allowed in section names. Each
       variable must belong to some section, which means that there must be a section header
       before the first setting of a variable.

       Sections can be further divided into subsections. To begin a subsection put its name in
       double quotes, separated by space from the section name, in the section header, like in
       the example below:

		   [section "subsection"]

       Subsection names are case sensitive and can contain any characters except newline
       (doublequote " and backslash have to be escaped as \" and \\, respectively). Section
       headers cannot span multiple lines. Variables may belong directly to a section or to a
       given subsection. You can have [section] if you have [section "subsection"], but you don't
       need to.

       There is also a deprecated [section.subsection] syntax. With this syntax, the subsection
       name is converted to lower-case and is also compared case sensitively. These subsection
       names follow the same restrictions as section names.

       All the other lines (and the remainder of the line after the section header) are
       recognized as setting variables, in the form name = value. If there is no equal sign on
       the line, the entire line is taken as name and the variable is recognized as boolean
       "true". The variable names are case-insensitive, allow only alphanumeric characters and -,
       and must start with an alphabetic character. There can be more than one value for a given
       variable; we say then that the variable is multivalued.

       Leading and trailing whitespace in a variable value is discarded. Internal whitespace
       within a variable value is retained verbatim.

       The values following the equals sign in variable assign are all either a string, an
       integer, or a boolean. Boolean values may be given as yes/no, 1/0, true/false or on/off.
       Case is not significant in boolean values, when converting value to the canonical form
       using --bool type specifier; git config will ensure that the output is "true" or "false".

       String values may be entirely or partially enclosed in double quotes. You need to enclose
       variable values in double quotes if you want to preserve leading or trailing whitespace,
       or if the variable value contains comment characters (i.e. it contains # or ;). Double
       quote " and backslash \ characters in variable values must be escaped: use \" for " and \\
       for \.

       The following escape sequences (beside \" and \\) are recognized: \n for newline character
       (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). No other char
       escape sequence, nor octal char sequences are valid.

       Variable values ending in a \ are continued on the next line in the customary UNIX
       fashion.

       Some variables may require a special value format.

   Includes
       You can include one config file from another by setting the special include.path variable
       to the name of the file to be included. The included file is expanded immediately, as if
       its contents had been found at the location of the include directive. If the value of the
       include.path variable is a relative path, the path is considered to be relative to the
       configuration file in which the include directive was found. The value of include.path is
       subject to tilde expansion: ~/ is expanded to the value of $HOME, and ~user/ to the
       specified user's home directory. See below for examples.

   Example
	   # Core variables
	   [core]
		   ; Don't trust file modes
		   filemode = false

	   # Our diff algorithm
	   [diff]
		   external = /usr/local/bin/diff-wrapper
		   renames = true

	   [branch "devel"]
		   remote = origin
		   merge = refs/heads/devel

	   # Proxy settings
	   [core]
		   gitProxy="ssh" for "kernel.org"
		   gitProxy=default-proxy ; for the rest

	   [include]
		   path = /path/to/foo.inc ; include by absolute path
		   path = foo ; expand "foo" relative to the current file
		   path = ~/foo ; expand "foo" in your $HOME directory

   Variables
       Note that this list is non-comprehensive and not necessarily complete. For
       command-specific variables, you will find a more detailed description in the appropriate
       manual page. You will find a description of non-core porcelain configuration variables in
       the respective porcelain documentation.

       advice.*
	   These variables control various optional help messages designed to aid new users. All
	   advice.*  variables default to true, and you can tell Git that you do not need help by
	   setting these to false:

	   pushUpdateRejected
	       Set this variable to false if you want to disable pushNonFFCurrent,
	       pushNonFFDefault, pushNonFFMatching, pushAlreadyExists, pushFetchFirst, and
	       pushNeedsForce simultaneously.

	   pushNonFFCurrent
	       Advice shown when git-push(1) fails due to a non-fast-forward update to the
	       current branch.

	   pushNonFFDefault
	       Advice to set push.default to upstream or current when you ran git-push(1) and
	       pushed matching refs by default (i.e. you did not provide an explicit refspec, and
	       no push.default configuration was set) and it resulted in a non-fast-forward
	       error.

	   pushNonFFMatching
	       Advice shown when you ran git-push(1) and pushed matching refs explicitly (i.e.
	       you used :, or specified a refspec that isn't your current branch) and it resulted
	       in a non-fast-forward error.

	   pushAlreadyExists
	       Shown when git-push(1) rejects an update that does not qualify for fast-forwarding
	       (e.g., a tag.)

	   pushFetchFirst
	       Shown when git-push(1) rejects an update that tries to overwrite a remote ref that
	       points at an object we do not have.

	   pushNeedsForce
	       Shown when git-push(1) rejects an update that tries to overwrite a remote ref that
	       points at an object that is not a committish, or make the remote ref point at an
	       object that is not a committish.

	   statusHints
	       Show directions on how to proceed from the current state in the output of git-
	       status(1), in the template shown when writing commit messages in git-commit(1),
	       and in the help message shown by git-checkout(1) when switching branch.

	   statusUoption
	       Advise to consider using the -u option to git-status(1) when the command takes
	       more than 2 seconds to enumerate untracked files.

	   commitBeforeMerge
	       Advice shown when git-merge(1) refuses to merge to avoid overwriting local
	       changes.

	   resolveConflict
	       Advice shown by various commands when conflicts prevent the operation from being
	       performed.

	   implicitIdentity
	       Advice on how to set your identity configuration when your information is guessed
	       from the system username and domain name.

	   detachedHead
	       Advice shown when you used git-checkout(1) to move to the detach HEAD state, to
	       instruct how to create a local branch after the fact.

	   amWorkDir
	       Advice that shows the location of the patch file when git-am(1) fails to apply it.

       core.fileMode
	   If false, the executable bit differences between the index and the working tree are
	   ignored; useful on broken filesystems like FAT. See git-update-index(1).

	   The default is true, except git-clone(1) or git-init(1) will probe and set
	   core.fileMode false if appropriate when the repository is created.

       core.ignoreCygwinFSTricks
	   This option is only used by Cygwin implementation of Git. If false, the Cygwin stat()
	   and lstat() functions are used. This may be useful if your repository consists of a
	   few separate directories joined in one hierarchy using Cygwin mount. If true, Git uses
	   native Win32 API whenever it is possible and falls back to Cygwin functions only to
	   handle symbol links. The native mode is more than twice faster than normal Cygwin
	   l/stat() functions. True by default, unless core.filemode is true, in which case
	   ignoreCygwinFSTricks is ignored as Cygwin's POSIX emulation is required to support
	   core.filemode.

       core.ignorecase
	   If true, this option enables various workarounds to enable Git to work better on
	   filesystems that are not case sensitive, like FAT. For example, if a directory listing
	   finds "makefile" when Git expects "Makefile", Git will assume it is really the same
	   file, and continue to remember it as "Makefile".

	   The default is false, except git-clone(1) or git-init(1) will probe and set
	   core.ignorecase true if appropriate when the repository is created.

       core.precomposeunicode
	   This option is only used by Mac OS implementation of Git. When
	   core.precomposeunicode=true, Git reverts the unicode decomposition of filenames done
	   by Mac OS. This is useful when sharing a repository between Mac OS and Linux or
	   Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When
	   false, file names are handled fully transparent by Git, which is backward compatible
	   with older versions of Git.

       core.trustctime
	   If false, the ctime differences between the index and the working tree are ignored;
	   useful when the inode change time is regularly modified by something outside Git (file
	   system crawlers and some backup systems). See git-update-index(1). True by default.

       core.checkstat
	   Determines which stat fields to match between the index and work tree. The user can
	   set this to default or minimal. Default (or explicitly default), is to check all
	   fields, including the sub-second part of mtime and ctime.

       core.quotepath
	   The commands that output paths (e.g.  ls-files, diff), when not given the -z option,
	   will quote "unusual" characters in the pathname by enclosing the pathname in a
	   double-quote pair and with backslashes the same way strings in C source code are
	   quoted. If this variable is set to false, the bytes higher than 0x80 are not quoted
	   but output as verbatim. Note that double quote, backslash and control characters are
	   always quoted without -z regardless of the setting of this variable.

       core.eol
	   Sets the line ending type to use in the working directory for files that have the text
	   property set. Alternatives are lf, crlf and native, which uses the platform's native
	   line ending. The default value is native. See gitattributes(5) for more information on
	   end-of-line conversion.

       core.safecrlf
	   If true, makes Git check if converting CRLF is reversible when end-of-line conversion
	   is active. Git will verify if a command modifies a file in the work tree either
	   directly or indirectly. For example, committing a file followed by checking out the
	   same file should yield the original file in the work tree. If this is not the case for
	   the current setting of core.autocrlf, Git will reject the file. The variable can be
	   set to "warn", in which case Git will only warn about an irreversible conversion but
	   continue the operation.

	   CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will
	   convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains
	   a mixture of LF and CRLF before the commit cannot be recreated by Git. For text files
	   this is the right thing to do: it corrects line endings such that we have only LF line
	   endings in the repository. But for binary files that are accidentally classified as
	   text the conversion can corrupt data.

	   If you recognize such corruption early you can easily fix it by setting the conversion
	   type explicitly in .gitattributes. Right after committing you still have the original
	   file in your work tree and this file is not yet corrupted. You can explicitly tell Git
	   that this file is binary and Git will handle the file appropriately.

	   Unfortunately, the desired effect of cleaning up text files with mixed line endings
	   and the undesired effect of corrupting binary files cannot be distinguished. In both
	   cases CRLFs are removed in an irreversible way. For text files this is the right thing
	   to do because CRLFs are line endings, while for binary files converting CRLFs corrupts
	   data.

	   Note, this safety check does not mean that a checkout will generate a file identical
	   to the original file for a different setting of core.eol and core.autocrlf, but only
	   for the current one. For example, a text file with LF would be accepted with
	   core.eol=lf and could later be checked out with core.eol=crlf, in which case the
	   resulting file would contain CRLF, although the original file contained LF. However,
	   in both work trees the line endings would be consistent, that is either all LF or all
	   CRLF, but never mixed. A file with mixed line endings would be reported by the
	   core.safecrlf mechanism.

       core.autocrlf
	   Setting this variable to "true" is almost the same as setting the text attribute to
	   "auto" on all files except that text files are not guaranteed to be normalized: files
	   that contain CRLF in the repository will not be touched. Use this setting if you want
	   to have CRLF line endings in your working directory even though the repository does
	   not have normalized line endings. This variable can be set to input, in which case no
	   output conversion is performed.

       core.symlinks
	   If false, symbolic links are checked out as small plain files that contain the link
	   text.  git-update-index(1) and git-add(1) will not change the recorded type to regular
	   file. Useful on filesystems like FAT that do not support symbolic links.

	   The default is true, except git-clone(1) or git-init(1) will probe and set
	   core.symlinks false if appropriate when the repository is created.

       core.gitProxy
	   A "proxy command" to execute (as command host port) instead of establishing direct
	   connection to the remote server when using the Git protocol for fetching. If the
	   variable value is in the "COMMAND for DOMAIN" format, the command is applied only on
	   hostnames ending with the specified domain string. This variable may be set multiple
	   times and is matched in the given order; the first match wins.

	   Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies
	   universally, without the special "for" handling).

	   The special string none can be used as the proxy command to specify that no proxy be
	   used for a given domain pattern. This is useful for excluding servers inside a
	   firewall from proxy use, while defaulting to a common proxy for external domains.

       core.ignoreStat
	   If true, commands which modify both the working tree and the index will mark the
	   updated paths with the "assume unchanged" bit in the index. These marked files are
	   then assumed to stay unchanged in the working tree, until you mark them otherwise
	   manually - Git will not detect the file changes by lstat() calls. This is useful on
	   systems where those are very slow, such as Microsoft Windows. See git-update-index(1).
	   False by default.

       core.preferSymlinkRefs
	   Instead of the default "symref" format for HEAD and other symbolic reference files,
	   use symbolic links. This is sometimes needed to work with old scripts that expect HEAD
	   to be a symbolic link.

       core.bare
	   If true this repository is assumed to be bare and has no working directory associated
	   with it. If this is the case a number of commands that require a working directory
	   will be disabled, such as git-add(1) or git-merge(1).

	   This setting is automatically guessed by git-clone(1) or git-init(1) when the
	   repository was created. By default a repository that ends in "/.git" is assumed to be
	   not bare (bare = false), while all other repositories are assumed to be bare (bare =
	   true).

       core.worktree
	   Set the path to the root of the working tree. This can be overridden by the
	   GIT_WORK_TREE environment variable and the --work-tree command line option. The value
	   can be an absolute path or relative to the path to the .git directory, which is either
	   specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or
	   GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is
	   specified, the current working directory is regarded as the top level of your working
	   tree.

	   Note that this variable is honored even when set in a configuration file in a ".git"
	   subdirectory of a directory and its value differs from the latter directory (e.g.
	   "/path/to/.git/config" has core.worktree set to "/different/path"), which is most
	   likely a misconfiguration. Running Git commands in the "/path/to" directory will still
	   use "/different/path" as the root of the work tree and can cause confusion unless you
	   know what you are doing (e.g. you are creating a read-only snapshot of the same index
	   to a location different from the repository's usual working tree).

       core.logAllRefUpdates
	   Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>",
	   by appending the new and old SHA-1, the date/time and the reason of the update, but
	   only when the file exists. If this configuration variable is set to true, missing
	   "$GIT_DIR/logs/<ref>" file is automatically created for branch heads (i.e. under
	   refs/heads/), remote refs (i.e. under refs/remotes/), note refs (i.e. under
	   refs/notes/), and the symbolic ref HEAD.

	   This information can be used to determine what commit was the tip of a branch "2 days
	   ago".

	   This value is true by default in a repository that has a working directory associated
	   with it, and false by default in a bare repository.

       core.repositoryFormatVersion
	   Internal variable identifying the repository format and layout version.

       core.sharedRepository
	   When group (or true), the repository is made shareable between several users in a
	   group (making sure all the files and objects are group-writable). When all (or world
	   or everybody), the repository will be readable by all users, additionally to being
	   group-shareable. When umask (or false), Git will use permissions reported by umask(2).
	   When 0xxx, where 0xxx is an octal number, files in the repository will have this mode
	   value.  0xxx will override user's umask value (whereas the other options will only
	   override requested parts of the user's umask value). Examples: 0660 will make the repo
	   read/write-able for the owner and group, but inaccessible to others (equivalent to
	   group unless umask is e.g.  0022).  0640 is a repository that is group-readable but
	   not group-writable. See git-init(1). False by default.

       core.warnAmbiguousRefs
	   If true, Git will warn you if the ref name you passed it is ambiguous and might match
	   multiple refs in the repository. True by default.

       core.compression
	   An integer -1..9, indicating a default compression level. -1 is the zlib default. 0
	   means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If
	   set, this provides a default to other compression variables, such as
	   core.loosecompression and pack.compression.

       core.loosecompression
	   An integer -1..9, indicating the compression level for objects that are not in a pack
	   file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size
	   tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not
	   set, defaults to 1 (best speed).

       core.packedGitWindowSize
	   Number of bytes of a pack file to map into memory in a single mapping operation.
	   Larger window sizes may allow your system to process a smaller number of large pack
	   files more quickly. Smaller window sizes will negatively affect performance due to
	   increased calls to the operating system's memory manager, but may improve performance
	   when accessing a large number of large pack files.

	   Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit
	   platforms and 1 GiB on 64 bit platforms. This should be reasonable for all
	   users/operating systems. You probably do not need to adjust this value.

	   Common unit suffixes of k, m, or g are supported.

       core.packedGitLimit
	   Maximum number of bytes to map simultaneously into memory from pack files. If Git
	   needs to access more than this many bytes at once to complete an operation it will
	   unmap existing regions to reclaim virtual address space within the process.

	   Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be
	   reasonable for all users/operating systems, except on the largest projects. You
	   probably do not need to adjust this value.

	   Common unit suffixes of k, m, or g are supported.

       core.deltaBaseCacheLimit
	   Maximum number of bytes to reserve for caching base objects that may be referenced by
	   multiple deltified objects. By storing the entire decompressed base objects in a cache
	   Git is able to avoid unpacking and decompressing frequently used base objects multiple
	   times.

	   Default is 16 MiB on all platforms. This should be reasonable for all users/operating
	   systems, except on the largest projects. You probably do not need to adjust this
	   value.

	   Common unit suffixes of k, m, or g are supported.

       core.bigFileThreshold
	   Files larger than this size are stored deflated, without attempting delta compression.
	   Storing large files without delta compression avoids excessive memory usage, at the
	   slight expense of increased disk usage.

	   Default is 512 MiB on all platforms. This should be reasonable for most projects as
	   source code and other text files can still be delta compressed, but larger binary
	   media files won't be.

	   Common unit suffixes of k, m, or g are supported.

       core.excludesfile
	   In addition to .gitignore (per-directory) and .git/info/exclude, Git looks into this
	   file for patterns of files which are not meant to be tracked. "~/" is expanded to the
	   value of $HOME and "~user/" to the specified user's home directory. Its default value
	   is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty,
	   $HOME/.config/git/ignore is used instead. See gitignore(5).

       core.askpass
	   Some commands (e.g. svn and http interfaces) that interactively ask for a password can
	   be told to use an external program given via the value of this variable. Can be
	   overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value
	   of the SSH_ASKPASS environment variable or, failing that, a simple password prompt.
	   The external program shall be given a suitable prompt as command line argument and
	   write the password on its STDOUT.

       core.attributesfile
	   In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into
	   this file for attributes (see gitattributes(5)). Path expansions are made the same way
	   as for core.excludesfile. Its default value is $XDG_CONFIG_HOME/git/attributes. If
	   $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/attributes is used
	   instead.

       core.editor
	   Commands such as commit and tag that lets you edit messages by launching an editor
	   uses the value of this variable when it is set, and the environment variable
	   GIT_EDITOR is not set. See git-var(1).

       core.commentchar
	   Commands such as commit and tag that lets you edit messages consider a line that
	   begins with this character commented, and removes them after the editor returns
	   (default #).

       sequence.editor
	   Text editor used by git rebase -i for editing the rebase instruction file. The value
	   is meant to be interpreted by the shell when it is used. It can be overridden by the
	   GIT_SEQUENCE_EDITOR environment variable. When not configured the default commit
	   message editor is used instead.

       core.pager
	   The command that Git will use to paginate output. Can be overridden with the GIT_PAGER
	   environment variable. Note that Git sets the LESS environment variable to FRSX if it
	   is unset when it runs the pager. One can change these settings by setting the LESS
	   variable to some other value. Alternately, these settings can be overridden on a
	   project or global basis by setting the core.pager option. Setting core.pager has no
	   effect on the LESS environment variable behaviour above, so if you want to override
	   Git's default settings this way, you need to be explicit. For example, to disable the
	   S option in a backward compatible manner, set core.pager to less -+S. This will be
	   passed to the shell by Git, which will translate the final command to LESS=FRSX less
	   -+S.

       core.whitespace
	   A comma separated list of common whitespace problems to notice.  git diff will use
	   color.diff.whitespace to highlight them, and git apply --whitespace=error will
	   consider them as errors. You can prefix - to disable any of them (e.g.
	   -trailing-space):

	   o   blank-at-eol treats trailing whitespaces at the end of the line as an error
	       (enabled by default).

	   o   space-before-tab treats a space character that appears immediately before a tab
	       character in the initial indent part of the line as an error (enabled by default).

	   o   indent-with-non-tab treats a line that is indented with space characters instead
	       of the equivalent tabs as an error (not enabled by default).

	   o   tab-in-indent treats a tab character in the initial indent part of the line as an
	       error (not enabled by default).

	   o   blank-at-eof treats blank lines added at the end of file as an error (enabled by
	       default).

	   o   trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof.

	   o   cr-at-eol treats a carriage-return at the end of line as part of the line
	       terminator, i.e. with it, trailing-space does not trigger if the character before
	       such a carriage-return is not a whitespace (not enabled by default).

	   o   tabwidth=<n> tells how many character positions a tab occupies; this is relevant
	       for indent-with-non-tab and when Git fixes tab-in-indent errors. The default tab
	       width is 8. Allowed values are 1 to 63.

       core.fsyncobjectfiles
	   This boolean will enable fsync() when writing object files.

	   This is a total waste of time and effort on a filesystem that orders data writes
	   properly, but can be useful for filesystems that do not use journalling (traditional
	   UNIX filesystems) or that only journal metadata and not file contents (OS X's HFS+, or
	   Linux ext3 with "data=writeback").

       core.preloadindex
	   Enable parallel index preload for operations like git diff

	   This can speed up operations like git diff and git status especially on filesystems
	   like NFS that have weak caching semantics and thus relatively high IO latencies. With
	   this set to true, Git will do the index comparison to the filesystem data in parallel,
	   allowing overlapping IO's.

       core.createObject
	   You can set this to link, in which case a hardlink followed by a delete of the source
	   are used to make sure that object creation will not overwrite existing objects.

	   On some file system/operating system combinations, this is unreliable. Set this config
	   setting to rename there; However, This will remove the check that makes sure that
	   existing object files will not get overwritten.

       core.notesRef
	   When showing commit messages, also show notes which are stored in the given ref. The
	   ref must be fully qualified. If the given ref does not exist, it is not an error but
	   means that no notes should be printed.

	   This setting defaults to "refs/notes/commits", and it can be overridden by the
	   GIT_NOTES_REF environment variable. See git-notes(1).

       core.sparseCheckout
	   Enable "sparse checkout" feature. See section "Sparse checkout" in git-read-tree(1)
	   for more information.

       core.abbrev
	   Set the length object names are abbreviated to. If unspecified, many commands
	   abbreviate to 7 hexdigits, which may not be enough for abbreviated object names to
	   stay unique for sufficiently long time.

       add.ignore-errors, add.ignoreErrors
	   Tells git add to continue adding files when some files cannot be added due to indexing
	   errors. Equivalent to the --ignore-errors option of git-add(1). Older versions of Git
	   accept only add.ignore-errors, which does not follow the usual naming convention for
	   configuration variables. Newer versions of Git honor add.ignoreErrors as well.

       alias.*
	   Command aliases for the git(1) command wrapper - e.g. after defining "alias.last =
	   cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit
	   HEAD". To avoid confusion and troubles with script usage, aliases that hide existing
	   Git commands are ignored. Arguments are split by spaces, the usual shell quoting and
	   escaping is supported. quote pair and a backslash can be used to quote them.

	   If the alias expansion is prefixed with an exclamation point, it will be treated as a
	   shell command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the
	   invocation "git new" is equivalent to running the shell command "gitk --all --not
	   ORIG_HEAD". Note that shell commands will be executed from the top-level directory of
	   a repository, which may not necessarily be the current directory.  GIT_PREFIX is set
	   as returned by running git rev-parse --show-prefix from the original current
	   directory. See git-rev-parse(1).

       am.keepcr
	   If true, git-am will call git-mailsplit for patches in mbox format with parameter
	   --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n.
	   Can be overridden by giving --no-keep-cr from the command line. See git-am(1), git-
	   mailsplit(1).

       apply.ignorewhitespace
	   When set to change, tells git apply to ignore changes in whitespace, in the same way
	   as the --ignore-space-change option. When set to one of: no, none, never, false tells
	   git apply to respect all whitespace differences. See git-apply(1).

       apply.whitespace
	   Tells git apply how to handle whitespaces, in the same way as the --whitespace option.
	   See git-apply(1).

       branch.autosetupmerge
	   Tells git branch and git checkout to set up new branches so that git-pull(1) will
	   appropriately merge from the starting point branch. Note that even if this option is
	   not set, this behavior can be chosen per-branch using the --track and --no-track
	   options. The valid settings are: false -- no automatic setup is done; true --
	   automatic setup is done when the starting point is a remote-tracking branch; always --
	   automatic setup is done when the starting point is either a local branch or
	   remote-tracking branch. This option defaults to true.

       branch.autosetuprebase
	   When a new branch is created with git branch or git checkout that tracks another
	   branch, this variable tells Git to set up pull to rebase instead of merge (see
	   "branch.<name>.rebase"). When never, rebase is never automatically set to true. When
	   local, rebase is set to true for tracked branches of other local branches. When
	   remote, rebase is set to true for tracked branches of remote-tracking branches. When
	   always, rebase will be set to true for all tracking branches. See
	   "branch.autosetupmerge" for details on how to set up a branch to track another branch.
	   This option defaults to never.

       branch.<name>.remote
	   When on branch <name>, it tells git fetch and git push which remote to fetch from/push
	   to. The remote to push to may be overridden with remote.pushdefault (for all
	   branches). The remote to push to, for the current branch, may be further overridden by
	   branch.<name>.pushremote. If no remote is configured, or if you are not on any branch,
	   it defaults to origin for fetching and remote.pushdefault for pushing.

       branch.<name>.pushremote
	   When on branch <name>, it overrides branch.<name>.remote for pushing. It also
	   overrides remote.pushdefault for pushing from branch <name>. When you pull from one
	   place (e.g. your upstream) and push to another place (e.g. your own publishing
	   repository), you would want to set remote.pushdefault to specify the remote to push to
	   for all branches, and use this option to override it for a specific branch.

       branch.<name>.merge
	   Defines, together with branch.<name>.remote, the upstream branch for the given branch.
	   It tells git fetch/git pull/git rebase which branch to merge and can also affect git
	   push (see push.default). When in branch <name>, it tells git fetch the default refspec
	   to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a
	   refspec, and must match a ref which is fetched from the remote given by
	   "branch.<name>.remote". The merge information is used by git pull (which at first
	   calls git fetch) to lookup the default branch for merging. Without this option, git
	   pull defaults to merge the first refspec fetched. Specify multiple values to get an
	   octopus merge. If you wish to setup git pull so that it merges into <name> from
	   another branch in the local repository, you can point branch.<name>.merge to the
	   desired branch, and use the special setting .  (a period) for branch.<name>.remote.

       branch.<name>.mergeoptions
	   Sets default options for merging into branch <name>. The syntax and supported options
	   are the same as those of git-merge(1), but option values containing whitespace
	   characters are currently not supported.

       branch.<name>.rebase
	   When true, rebase the branch <name> on top of the fetched branch, instead of merging
	   the default branch from the default remote when "git pull" is run. See "pull.rebase"
	   for doing this in a non branch-specific manner.

	   NOTE: this is a possibly dangerous operation; do not use it unless you understand the
	   implications (see git-rebase(1) for details).

       branch.<name>.description
	   Branch description, can be edited with git branch --edit-description. Branch
	   description is automatically added in the format-patch cover letter or request-pull
	   summary.

       browser.<tool>.cmd
	   Specify the command to invoke the specified browser. The specified command is
	   evaluated in shell with the URLs passed as arguments. (See git-web--browse(1).)

       browser.<tool>.path
	   Override the path for the given tool that may be used to browse HTML help (see -w
	   option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)).

       clean.requireForce
	   A boolean to make git-clean do nothing unless given -f or -n. Defaults to true.

       color.branch
	   A boolean to enable/disable color in the output of git-branch(1). May be set to
	   always, false (or never) or auto (or true), in which case colors are used only when
	   the output is to a terminal. Defaults to false.

       color.branch.<slot>
	   Use customized color for branch coloration.	<slot> is one of current (the current
	   branch), local (a local branch), remote (a remote-tracking branch in refs/remotes/),
	   upstream (upstream tracking branch), plain (other refs).

	   The value for these configuration variables is a list of colors (at most two) and
	   attributes (at most one), separated by spaces. The colors accepted are normal, black,
	   red, green, yellow, blue, magenta, cyan and white; the attributes are bold, dim, ul,
	   blink and reverse. The first color given is the foreground; the second is the
	   background. The position of the attribute, if any, doesn't matter.

       color.diff
	   Whether to use ANSI escape sequences to add color to patches. If this is set to
	   always, git-diff(1), git-log(1), and git-show(1) will use color for all patches. If it
	   is set to true or auto, those commands will only use color when output is to the
	   terminal. Defaults to false.

	   This does not affect git-format-patch(1) nor the git-diff-* plumbing commands. Can be
	   overridden on the command line with the --color[=<when>] option.

       color.diff.<slot>
	   Use customized color for diff colorization.	<slot> specifies which part of the patch
	   to use the specified color, and is one of plain (context text), meta
	   (metainformation), frag (hunk header), func (function in hunk header), old (removed
	   lines), new (added lines), commit (commit headers), or whitespace (highlighting
	   whitespace errors). The values of these variables may be specified as in
	   color.branch.<slot>.

       color.decorate.<slot>
	   Use customized color for git log --decorate output.	<slot> is one of branch,
	   remoteBranch, tag, stash or HEAD for local branches, remote-tracking branches, tags,
	   stash and HEAD, respectively.

       color.grep
	   When set to always, always highlight matches. When false (or never), never. When set
	   to true or auto, use color only when the output is written to the terminal. Defaults
	   to false.

       color.grep.<slot>
	   Use customized color for grep colorization.	<slot> specifies which part of the line
	   to use the specified color, and is one of

	   context
	       non-matching text in context lines (when using -A, -B, or -C)

	   filename
	       filename prefix (when not using -h)

	   function
	       function name lines (when using -p)

	   linenumber
	       line number prefix (when using -n)

	   match
	       matching text

	   selected
	       non-matching text in selected lines

	   separator
	       separators between fields on a line (:, -, and =) and between hunks (--)

	   The values of these variables may be specified as in color.branch.<slot>.

       color.interactive
	   When set to always, always use colors for interactive prompts and displays (such as
	   those used by "git-add --interactive"). When false (or never), never. When set to true
	   or auto, use colors only when the output is to the terminal. Defaults to false.

       color.interactive.<slot>
	   Use customized color for git add --interactive output.  <slot> may be prompt, header,
	   help or error, for four distinct types of normal output from interactive commands. The
	   values of these variables may be specified as in color.branch.<slot>.

       color.pager
	   A boolean to enable/disable colored output when the pager is in use (default is true).

       color.showbranch
	   A boolean to enable/disable color in the output of git-show-branch(1). May be set to
	   always, false (or never) or auto (or true), in which case colors are used only when
	   the output is to a terminal. Defaults to false.

       color.status
	   A boolean to enable/disable color in the output of git-status(1). May be set to
	   always, false (or never) or auto (or true), in which case colors are used only when
	   the output is to a terminal. Defaults to false.

       color.status.<slot>
	   Use customized color for status colorization.  <slot> is one of header (the header
	   text of the status message), added or updated (files which are added but not
	   committed), changed (files which are changed but not added in the index), untracked
	   (files which are not tracked by Git), branch (the current branch), or nobranch (the
	   color the no branch warning is shown in, defaulting to red). The values of these
	   variables may be specified as in color.branch.<slot>.

       color.ui
	   This variable determines the default value for variables such as color.diff and
	   color.grep that control the use of color per command family. Its scope will expand as
	   more commands learn configuration to set a default for the --color option. Set it to
	   always if you want all output not intended for machine consumption to use color, to
	   true or auto if you want such output to use color when written to the terminal, or to
	   false or never if you prefer Git commands not to use color unless enabled explicitly
	   with some other configuration or the --color option.

       column.ui
	   Specify whether supported commands should output in columns. This variable consists of
	   a list of tokens separated by spaces or commas:

	   always
	       always show in columns

	   never
	       never show in columns

	   auto
	       show in columns if the output is to the terminal

	   column
	       fill columns before rows (default)

	   row
	       fill rows before columns

	   plain
	       show in one column

	   dense
	       make unequal size columns to utilize more space

	   nodense
	       make equal size columns

	   This option defaults to never.

       column.branch
	   Specify whether to output branch listing in git branch in columns. See column.ui for
	   details.

       column.status
	   Specify whether to output untracked files in git status in columns. See column.ui for
	   details.

       column.tag
	   Specify whether to output tag listing in git tag in columns. See column.ui for
	   details.

       commit.cleanup
	   This setting overrides the default of the --cleanup option in git commit. See git-
	   commit(1) for details. Changing the default can be useful when you always want to keep
	   lines that begin with comment character # in your log message, in which case you would
	   do git config commit.cleanup whitespace (note that you will have to remove the help
	   lines that begin with # in the commit log template yourself, if you do this).

       commit.status
	   A boolean to enable/disable inclusion of status information in the commit message
	   template when using an editor to prepare the commit message. Defaults to true.

       commit.template
	   Specify a file to use as the template for new commit messages. "~/" is expanded to the
	   value of $HOME and "~user/" to the specified user's home directory.

       credential.helper
	   Specify an external helper to be called when a username or password credential is
	   needed; the helper may consult external storage to avoid prompting the user for the
	   credentials. See gitcredentials(7) for details.

       credential.useHttpPath
	   When acquiring credentials, consider the "path" component of an http or https URL to
	   be important. Defaults to false. See gitcredentials(7) for more information.

       credential.username
	   If no username is set for a network authentication, use this username by default. See
	   credential.<context>.* below, and gitcredentials(7).

       credential.<url>.*
	   Any of the credential.* options above can be applied selectively to some credentials.
	   For example "credential.https://example.com.username" would set the default username
	   only for https connections to example.com. See gitcredentials(7) for details on how
	   URLs are matched.

       diff.autorefreshindex
	   When using git diff to compare with work tree files, do not consider stat-only change
	   as changed. Instead, silently run git update-index --refresh to update the cached stat
	   information for paths whose contents in the work tree match the contents in the index.
	   This option defaults to true. Note that this affects only git diff Porcelain, and not
	   lower level diff commands such as git diff-files.

       diff.dirstat
	   A comma separated list of --dirstat parameters specifying the default behavior of the
	   --dirstat option to git-diff(1)` and friends. The defaults can be overridden on the
	   command line (using --dirstat=<param1,param2,...>). The fallback defaults (when not
	   changed by diff.dirstat) are changes,noncumulative,3. The following parameters are
	   available:

	   changes
	       Compute the dirstat numbers by counting the lines that have been removed from the
	       source, or added to the destination. This ignores the amount of pure code
	       movements within a file. In other words, rearranging lines in a file is not
	       counted as much as other changes. This is the default behavior when no parameter
	       is given.

	   lines
	       Compute the dirstat numbers by doing the regular line-based diff analysis, and
	       summing the removed/added line counts. (For binary files, count 64-byte chunks
	       instead, since binary files have no natural concept of lines). This is a more
	       expensive --dirstat behavior than the changes behavior, but it does count
	       rearranged lines within a file as much as other changes. The resulting output is
	       consistent with what you get from the other --*stat options.

	   files
	       Compute the dirstat numbers by counting the number of files changed. Each changed
	       file counts equally in the dirstat analysis. This is the computationally cheapest
	       --dirstat behavior, since it does not have to look at the file contents at all.

	   cumulative
	       Count changes in a child directory for the parent directory as well. Note that
	       when using cumulative, the sum of the percentages reported may exceed 100%. The
	       default (non-cumulative) behavior can be specified with the noncumulative
	       parameter.

	   <limit>
	       An integer parameter specifies a cut-off percent (3% by default). Directories
	       contributing less than this percentage of the changes are not shown in the output.

	   Example: The following will count changed files, while ignoring directories with less
	   than 10% of the total amount of changed files, and accumulating child directory counts
	   in the parent directories: files,10,cumulative.

       diff.statGraphWidth
	   Limit the width of the graph part in --stat output. If set, applies to all commands
	   generating --stat output except format-patch.

       diff.context
	   Generate diffs with <n> lines of context instead of the default of 3. This value is
	   overridden by the -U option.

       diff.external
	   If this config variable is set, diff generation is not performed using the internal
	   diff machinery, but using the given command. Can be overridden with the
	   'GIT_EXTERNAL_DIFF' environment variable. The command is called with parameters as
	   described under "git Diffs" in git(1). Note: if you want to use an external diff
	   program only on a subset of your files, you might want to use gitattributes(5)
	   instead.

       diff.ignoreSubmodules
	   Sets the default value of --ignore-submodules. Note that this affects only git diff
	   Porcelain, and not lower level diff commands such as git diff-files.  git checkout
	   also honors this setting when reporting uncommitted changes.

       diff.mnemonicprefix
	   If set, git diff uses a prefix pair that is different from the standard "a/" and "b/"
	   depending on what is being compared. When this configuration is in effect, reverse
	   diff output also swaps the order of the prefixes:

	   git diff
	       compares the (i)ndex and the (w)ork tree;

	   git diff HEAD
	       compares a (c)ommit and the (w)ork tree;

	   git diff --cached
	       compares a (c)ommit and the (i)ndex;

	   git diff HEAD:file1 file2
	       compares an (o)bject and a (w)ork tree entity;

	   git diff --no-index a b
	       compares two non-git things (1) and (2).

       diff.noprefix
	   If set, git diff does not show any source or destination prefix.

       diff.renameLimit
	   The number of files to consider when performing the copy/rename detection; equivalent
	   to the git diff option -l.

       diff.renames
	   Tells Git to detect renames. If set to any boolean value, it will enable basic rename
	   detection. If set to "copies" or "copy", it will detect copies, as well.

       diff.suppressBlankEmpty
	   A boolean to inhibit the standard behavior of printing a space before each empty
	   output line. Defaults to false.

       diff.submodule
	   Specify the format in which differences in submodules are shown. The "log" format
	   lists the commits in the range like git-submodule(1)summary does. The "short" format
	   format just shows the names of the commits at the beginning and end of the range.
	   Defaults to short.

       diff.wordRegex
	   A POSIX Extended Regular Expression used to determine what is a "word" when performing
	   word-by-word difference calculations. Character sequences that match the regular
	   expression are "words", all other characters are ignorable whitespace.

       diff.<driver>.command
	   The custom diff driver command. See gitattributes(5) for details.

       diff.<driver>.xfuncname
	   The regular expression that the diff driver should use to recognize the hunk header. A
	   built-in pattern may also be used. See gitattributes(5) for details.

       diff.<driver>.binary
	   Set this option to true to make the diff driver treat files as binary. See
	   gitattributes(5) for details.

       diff.<driver>.textconv
	   The command that the diff driver should call to generate the text-converted version of
	   a file. The result of the conversion is used to generate a human-readable diff. See
	   gitattributes(5) for details.

       diff.<driver>.wordregex
	   The regular expression that the diff driver should use to split words in a line. See
	   gitattributes(5) for details.

       diff.<driver>.cachetextconv
	   Set this option to true to make the diff driver cache the text conversion outputs. See
	   gitattributes(5) for details.

       diff.tool
	   Controls which diff tool is used by git-difftool(1). This variable overrides the value
	   configured in merge.tool. The list below shows the valid built-in values. Any other
	   value is treated as a custom diff tool and requires that a corresponding
	   difftool.<tool>.cmd variable is defined.

	   o   araxis

	   o   bc3

	   o   codecompare

	   o   deltawalker

	   o   diffuse

	   o   ecmerge

	   o   emerge

	   o   gvimdiff

	   o   gvimdiff2

	   o   kdiff3

	   o   kompare

	   o   meld

	   o   opendiff

	   o   p4merge

	   o   tkdiff

	   o   vimdiff

	   o   vimdiff2

	   o   xxdiff

       diff.algorithm
	   Choose a diff algorithm. The variants are as follows:

	   default, myers
	       The basic greedy diff algorithm. Currently, this is the default.

	   minimal
	       Spend extra time to make sure the smallest possible diff is produced.

	   patience
	       Use "patience diff" algorithm when generating patches.

	   histogram
	       This algorithm extends the patience algorithm to "support low-occurrence common
	       elements".

       difftool.<tool>.path
	   Override the path for the given tool. This is useful in case your tool is not in the
	   PATH.

       difftool.<tool>.cmd
	   Specify the command to invoke the specified diff tool. The specified command is
	   evaluated in shell with the following variables available: LOCAL is set to the name of
	   the temporary file containing the contents of the diff pre-image and REMOTE is set to
	   the name of the temporary file containing the contents of the diff post-image.

       difftool.prompt
	   Prompt before each invocation of the diff tool.

       fetch.recurseSubmodules
	   This option can be either set to a boolean value or to on-demand. Setting it to a
	   boolean changes the behavior of fetch and pull to unconditionally recurse into
	   submodules when set to true or to not recurse at all when set to false. When set to
	   on-demand (the default value), fetch and pull will only recurse into a populated
	   submodule when its superproject retrieves a commit that updates the submodule's
	   reference.

       fetch.fsckObjects
	   If it is set to true, git-fetch-pack will check all fetched objects. It will abort in
	   the case of a malformed object or a broken link. The result of an abort are only
	   dangling objects. Defaults to false. If not set, the value of transfer.fsckObjects is
	   used instead.

       fetch.unpackLimit
	   If the number of objects fetched over the Git native transfer is below this limit,
	   then the objects will be unpacked into loose object files. However if the number of
	   received objects equals or exceeds this limit then the received pack will be stored as
	   a pack, after adding any missing delta bases. Storing the pack from a push can make
	   the push operation complete faster, especially on slow filesystems. If not set, the
	   value of transfer.unpackLimit is used instead.

       format.attach
	   Enable multipart/mixed attachments as the default for format-patch. The value can also
	   be a double quoted string which will enable attachments as the default and set the
	   value as the boundary. See the --attach option in git-format-patch(1).

       format.numbered
	   A boolean which can enable or disable sequence numbers in patch subjects. It defaults
	   to "auto" which enables it only if there is more than one patch. It can be enabled or
	   disabled for all messages by setting it to "true" or "false". See --numbered option in
	   git-format-patch(1).

       format.headers
	   Additional email headers to include in a patch to be submitted by mail. See git-
	   format-patch(1).

       format.to, format.cc
	   Additional recipients to include in a patch to be submitted by mail. See the --to and
	   --cc options in git-format-patch(1).

       format.subjectprefix
	   The default for format-patch is to output files with the [PATCH] subject prefix. Use
	   this variable to change that prefix.

       format.signature
	   The default for format-patch is to output a signature containing the Git version
	   number. Use this variable to change that default. Set this variable to the empty
	   string ("") to suppress signature generation.

       format.suffix
	   The default for format-patch is to output files with the suffix .patch. Use this
	   variable to change that suffix (make sure to include the dot if you want it).

       format.pretty
	   The default pretty format for log/show/whatchanged command, See git-log(1), git-
	   show(1), git-whatchanged(1).

       format.thread
	   The default threading style for git format-patch. Can be a boolean value, or shallow
	   or deep.  shallow threading makes every mail a reply to the head of the series, where
	   the head is chosen from the cover letter, the --in-reply-to, and the first patch mail,
	   in this order.  deep threading makes every mail a reply to the previous one. A true
	   boolean value is the same as shallow, and a false value disables threading.

       format.signoff
	   A boolean value which lets you enable the -s/--signoff option of format-patch by
	   default.  Note: Adding the Signed-off-by: line to a patch should be a conscious act
	   and means that you certify you have the rights to submit this work under the same open
	   source license. Please see the SubmittingPatches document for further discussion.

       format.coverLetter
	   A boolean that controls whether to generate a cover-letter when format-patch is
	   invoked, but in addition can be set to "auto", to generate a cover-letter only when
	   there's more than one patch.

       filter.<driver>.clean
	   The command which is used to convert the content of a worktree file to a blob upon
	   checkin. See gitattributes(5) for details.

       filter.<driver>.smudge
	   The command which is used to convert the content of a blob object to a worktree file
	   upon checkout. See gitattributes(5) for details.

       gc.aggressiveWindow
	   The window size parameter used in the delta compression algorithm used by git gc
	   --aggressive. This defaults to 250.

       gc.auto
	   When there are approximately more than this many loose objects in the repository, git
	   gc --auto will pack them. Some Porcelain commands use this command to perform a
	   light-weight garbage collection from time to time. The default value is 6700. Setting
	   this to 0 disables it.

       gc.autopacklimit
	   When there are more than this many packs that are not marked with *.keep file in the
	   repository, git gc --auto consolidates them into one larger pack. The default value is
	   50. Setting this to 0 disables it.

       gc.packrefs
	   Running git pack-refs in a repository renders it unclonable by Git versions prior to
	   1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc
	   runs git pack-refs. This can be set to notbare to enable it within all non-bare repos
	   or it can be set to a boolean value. The default is true.

       gc.pruneexpire
	   When git gc is run, it will call prune --expire 2.weeks.ago. Override the grace period
	   with this config variable. The value "now" may be used to disable this grace period
	   and always prune unreachable objects immediately.

       gc.reflogexpire, gc.<pattern>.reflogexpire
	   git reflog expire removes reflog entries older than this time; defaults to 90 days.
	   With "<pattern>" (e.g. "refs/stash") in the middle the setting applies only to the
	   refs that match the <pattern>.

       gc.reflogexpireunreachable, gc.<ref>.reflogexpireunreachable
	   git reflog expire removes reflog entries older than this time and are not reachable
	   from the current tip; defaults to 30 days. With "<pattern>" (e.g. "refs/stash") in the
	   middle, the setting applies only to the refs that match the <pattern>.

       gc.rerereresolved
	   Records of conflicted merge you resolved earlier are kept for this many days when git
	   rerere gc is run. The default is 60 days. See git-rerere(1).

       gc.rerereunresolved
	   Records of conflicted merge you have not resolved are kept for this many days when git
	   rerere gc is run. The default is 15 days. See git-rerere(1).

       gitcvs.commitmsgannotation
	   Append this string to each commit message. Set to empty string to disable this
	   feature. Defaults to "via git-CVS emulator".

       gitcvs.enabled
	   Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

       gitcvs.logfile
	   Path to a log file where the CVS server interface well... logs various stuff. See git-
	   cvsserver(1).

       gitcvs.usecrlfattr
	   If true, the server will look up the end-of-line conversion attributes for files to
	   determine the -k modes to use. If the attributes force Git to treat a file as text,
	   the -k mode will be left blank so CVS clients will treat it as text. If they suppress
	   text conversion, the file will be set with -kb mode, which suppresses any newline
	   munging the client might otherwise do. If the attributes do not allow the file type to
	   be determined, then gitcvs.allbinary is used. See gitattributes(5).

       gitcvs.allbinary
	   This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If
	   true, all unresolved files are sent to the client in mode -kb. This causes the client
	   to treat them as binary files, which suppresses any newline munging it otherwise might
	   do. Alternatively, if it is set to "guess", then the contents of the file are examined
	   to decide if it is binary, similar to core.autocrlf.

       gitcvs.dbname
	   Database used by git-cvsserver to cache revision information derived from the Git
	   repository. The exact meaning depends on the used database driver, for SQLite (which
	   is the default driver) this is a filename. Supports variable substitution (see git-
	   cvsserver(1) for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite

       gitcvs.dbdriver
	   Used Perl DBI driver. You can specify any available driver for this here, but it might
	   not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and
	   reported not to work with DBD::mysql. Experimental feature. May not contain double
	   colons (:). Default: SQLite. See git-cvsserver(1).

       gitcvs.dbuser, gitcvs.dbpass
	   Database user and password. Only useful if setting gitcvs.dbdriver, since SQLite has
	   no concept of database users and/or passwords.  gitcvs.dbuser supports variable
	   substitution (see git-cvsserver(1) for details).

       gitcvs.dbTableNamePrefix
	   Database table name prefix. Prepended to the names of any database tables used,
	   allowing a single database to be used for several repositories. Supports variable
	   substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be
	   replaced with underscores.

       All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allbinary can also be
       specified as gitcvs.<access_method>.<varname> (where access_method is one of "ext" and
       "pserver") to make them apply only for the given access method.

       gitweb.category, gitweb.description, gitweb.owner, gitweb.url
	   See gitweb(1) for description.

       gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight, gitweb.patches,
       gitweb.pickaxe, gitweb.remote_heads, gitweb.showsizes, gitweb.snapshot
	   See gitweb.conf(5) for description.

       grep.lineNumber
	   If set to true, enable -n option by default.

       grep.patternType
	   Set the default matching behavior. Using a value of basic, extended, fixed, or perl
	   will enable the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp
	   option accordingly, while the value default will return to the default matching
	   behavior.

       grep.extendedRegexp
	   If set to true, enable --extended-regexp option by default. This option is ignored
	   when the grep.patternType option is set to a value other than default.

       gpg.program
	   Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP
	   signature. The program must support the same command line interface as GPG, namely, to
	   verify a detached signature, "gpg --verify $file - <$signature" is run, and the
	   program is expected to signal a good signature by exiting with code 0, and to generate
	   an ascii-armored detached signature, the standard input of "gpg -bsau $key" is fed
	   with the contents to be signed, and the program is expected to send the result to its
	   standard output.

       gui.commitmsgwidth
	   Defines how wide the commit message window is in the git-gui(1). "75" is the default.

       gui.diffcontext
	   Specifies how many context lines should be used in calls to diff made by the git-
	   gui(1). The default is "5".

       gui.encoding
	   Specifies the default encoding to use for displaying of file contents in git-gui(1)
	   and gitk(1). It can be overridden by setting the encoding attribute for relevant files
	   (see gitattributes(5)). If this option is not set, the tools default to the locale
	   encoding.

       gui.matchtrackingbranch
	   Determines if new branches created with git-gui(1) should default to tracking remote
	   branches with matching names or not. Default: "false".

       gui.newbranchtemplate
	   Is used as suggested name when creating new branches using the git-gui(1).

       gui.pruneduringfetch
	   "true" if git-gui(1) should prune remote-tracking branches when performing a fetch.
	   The default value is "false".

       gui.trustmtime
	   Determines if git-gui(1) should trust the file modification timestamp or not. By
	   default the timestamps are not trusted.

       gui.spellingdictionary
	   Specifies the dictionary used for spell checking commit messages in the git-gui(1).
	   When set to "none" spell checking is turned off.

       gui.fastcopyblame
	   If true, git gui blame uses -C instead of -C -C for original location detection. It
	   makes blame significantly faster on huge repositories at the expense of less thorough
	   copy detection.

       gui.copyblamethreshold
	   Specifies the threshold to use in git gui blame original location detection, measured
	   in alphanumeric characters. See the git-blame(1) manual for more information on copy
	   detection.

       gui.blamehistoryctx
	   Specifies the radius of history context in days to show in gitk(1) for the selected
	   commit, when the Show History Context menu item is invoked from git gui blame. If this
	   variable is set to zero, the whole history is shown.

       guitool.<name>.cmd
	   Specifies the shell command line to execute when the corresponding item of the git-
	   gui(1)Tools menu is invoked. This option is mandatory for every tool. The command is
	   executed from the root of the working directory, and in the environment it receives
	   the name of the tool as GIT_GUITOOL, the name of the currently selected file as
	   FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached,
	   CUR_BRANCH is empty).

       guitool.<name>.needsfile
	   Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not
	   empty.

       guitool.<name>.noconsole
	   Run the command silently, without creating a window to display its output.

       guitool.<name>.norescan
	   Don't rescan the working directory for changes after the tool finishes execution.

       guitool.<name>.confirm
	   Show a confirmation dialog before actually running the tool.

       guitool.<name>.argprompt
	   Request a string argument from the user, and pass it to the tool through the ARGS
	   environment variable. Since requesting an argument implies confirmation, the confirm
	   option has no effect if this is enabled. If the option is set to true, yes, or 1, the
	   dialog uses a built-in generic prompt; otherwise the exact value of the variable is
	   used.

       guitool.<name>.revprompt
	   Request a single valid revision from the user, and set the REVISION environment
	   variable. In other aspects this option is similar to argprompt, and can be used
	   together with it.

       guitool.<name>.revunmerged
	   Show only unmerged branches in the revprompt subdialog. This is useful for tools
	   similar to merge or rebase, but not for things like checkout or reset.

       guitool.<name>.title
	   Specifies the title to use for the prompt dialog. The default is the tool name.

       guitool.<name>.prompt
	   Specifies the general prompt string to display at the top of the dialog, before
	   subsections for argprompt and revprompt. The default value includes the actual
	   command.

       help.browser
	   Specify the browser that will be used to display help in the web format. See git-
	   help(1).

       help.format
	   Override the default help format used by git-help(1). Values man, info, web and html
	   are supported.  man is the default.	web and html are the same.

       help.autocorrect
	   Automatically correct and execute mistyped commands after waiting for the given number
	   of deciseconds (0.1 sec). If more than one command can be deduced from the entered
	   text, nothing will be executed. If the value of this option is negative, the corrected
	   command will be executed immediately. If the value is 0 - the command will be just
	   shown but not executed. This is the default.

       help.htmlpath
	   Specify the path where the HTML documentation resides. File system paths and URLs are
	   supported. HTML pages will be prefixed with this path when help is displayed in the
	   web format. This defaults to the documentation path of your Git installation.

       http.proxy
	   Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and
	   all_proxy environment variables (see curl(1)). This can be overridden on a per-remote
	   basis; see remote.<name>.proxy

       http.cookiefile
	   File containing previously stored cookie lines which should be used in the Git http
	   session, if they match the server. The file format of the file to read cookies from
	   should be plain HTTP headers or the Netscape/Mozilla cookie file format (see curl(1)).
	   NOTE that the file specified with http.cookiefile is only used as input. No cookies
	   will be stored in the file.

       http.sslVerify
	   Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be
	   overridden by the GIT_SSL_NO_VERIFY environment variable.

       http.sslCert
	   File containing the SSL certificate when fetching or pushing over HTTPS. Can be
	   overridden by the GIT_SSL_CERT environment variable.

       http.sslKey
	   File containing the SSL private key when fetching or pushing over HTTPS. Can be
	   overridden by the GIT_SSL_KEY environment variable.

       http.sslCertPasswordProtected
	   Enable Git's password prompt for the SSL certificate. Otherwise OpenSSL will prompt
	   the user, possibly many times, if the certificate or private key is encrypted. Can be
	   overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.sslCAInfo
	   File containing the certificates to verify the peer with when fetching or pushing over
	   HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

       http.sslCAPath
	   Path containing files with the CA certificates to verify the peer with when fetching
	   or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

       http.sslTry
	   Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular
	   FTP protocol. This might be needed if the FTP server requires it for security reasons
	   or you wish to connect securely whenever remote FTP server supports it. Default is
	   false since it might trigger certificate verification errors on misconfigured servers.

       http.maxRequests
	   How many HTTP requests to launch in parallel. Can be overridden by the
	   GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

       http.minSessions
	   The number of curl sessions (counted across slots) to be kept across requests. They
	   will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If
	   USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

       http.postBuffer
	   Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to
	   the remote system. For requests larger than this buffer size, HTTP/1.1 and
	   Transfer-Encoding: chunked is used to avoid creating a massive pack file locally.
	   Default is 1 MiB, which is sufficient for most requests.

       http.lowSpeedLimit, http.lowSpeedTime
	   If the HTTP transfer speed is less than http.lowSpeedLimit for longer than
	   http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the
	   GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

       http.noEPSV
	   A boolean which disables using of EPSV ftp command by curl. This can helpful with some
	   "poor" ftp servers which don't support EPSV mode. Can be overridden by the
	   GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

       http.useragent
	   The HTTP USER_AGENT string presented to an HTTP server. The default value represents
	   the version of the client Git such as git/1.7.1. This option allows you to override
	   this value to a more common value such as Mozilla/4.0. This may be necessary, for
	   instance, if connecting through a firewall that restricts HTTP connections to a set of
	   common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden
	   by the GIT_HTTP_USER_AGENT environment variable.

       i18n.commitEncoding
	   Character encoding the commit messages are stored in; Git itself does not care per se,
	   but this information is necessary e.g. when importing commits from emails or in the
	   gitk graphical history browser (and possibly at other places in the future or in other
	   porcelains). See e.g.  git-mailinfo(1). Defaults to utf-8.

       i18n.logOutputEncoding
	   Character encoding the commit messages are converted to when running git log and
	   friends.

       imap
	   The configuration variables in the imap section are described in git-imap-send(1).

       init.templatedir
	   Specify the directory from which templates will be copied. (See the "TEMPLATE
	   DIRECTORY" section of git-init(1).)

       instaweb.browser
	   Specify the program that will be used to browse your working repository in gitweb. See
	   git-instaweb(1).

       instaweb.httpd
	   The HTTP daemon command-line to start gitweb on your working repository. See git-
	   instaweb(1).

       instaweb.local
	   If true the web server started by git-instaweb(1) will be bound to the local IP
	   (127.0.0.1).

       instaweb.modulepath
	   The default module path for git-instaweb(1) to use instead of
	   /usr/lib/apache2/modules. Only used if httpd is Apache.

       instaweb.port
	   The port number to bind the gitweb httpd to. See git-instaweb(1).

       interactive.singlekey
	   In interactive commands, allow the user to provide one-letter input with a single key
	   (i.e., without hitting enter). Currently this is used by the --patch mode of git-
	   add(1), git-checkout(1), git-commit(1), git-reset(1), and git-stash(1). Note that this
	   setting is silently ignored if portable keystroke input is not available.

       log.abbrevCommit
	   If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --abbrev-commit.
	   You may override this option with --no-abbrev-commit.

       log.date
	   Set the default date-time mode for the log command. Setting a value for log.date is
	   similar to using git log's --date option. Possible values are relative, local,
	   default, iso, rfc, and short; see git-log(1) for details.

       log.decorate
	   Print out the ref names of any commits that are shown by the log command. If short is
	   specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be
	   printed. If full is specified, the full ref name (including prefix) will be printed.
	   This is the same as the log commands --decorate option.

       log.showroot
	   If true, the initial commit will be shown as a big creation event. This is equivalent
	   to a diff against an empty tree. Tools like git-log(1) or git-whatchanged(1), which
	   normally hide the root commit will now show it. True by default.

       log.mailmap
	   If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --use-mailmap.

       mailmap.file
	   The location of an augmenting mailmap file. The default mailmap, located in the root
	   of the repository, is loaded first, then the mailmap file pointed to by this variable.
	   The location of the mailmap file may be in a repository subdirectory, or somewhere
	   outside of the repository itself. See git-shortlog(1) and git-blame(1).

       mailmap.blob
	   Like mailmap.file, but consider the value as a reference to a blob in the repository.
	   If both mailmap.file and mailmap.blob are given, both are parsed, with entries from
	   mailmap.file taking precedence. In a bare repository, this defaults to HEAD:.mailmap.
	   In a non-bare repository, it defaults to empty.

       man.viewer
	   Specify the programs that may be used to display help in the man format. See git-
	   help(1).

       man.<tool>.cmd
	   Specify the command to invoke the specified man viewer. The specified command is
	   evaluated in shell with the man page passed as argument. (See git-help(1).)

       man.<tool>.path
	   Override the path for the given tool that may be used to display help in the man
	   format. See git-help(1).

       merge.conflictstyle
	   Specify the style in which conflicted hunks are written out to working tree files upon
	   merge. The default is "merge", which shows a <<<<<<< conflict marker, changes made by
	   one side, a ======= marker, changes made by the other side, and then a >>>>>>> marker.
	   An alternate style, "diff3", adds a ||||||| marker and the original text before the
	   ======= marker.

       merge.defaultToUpstream
	   If merge is called without any commit argument, merge the upstream branches configured
	   for the current branch by using their last observed values stored in their
	   remote-tracking branches. The values of the branch.<current branch>.merge that name
	   the branches at the remote named by branch.<current branch>.remote are consulted, and
	   then they are mapped via remote.<remote>.fetch to their corresponding remote-tracking
	   branches, and the tips of these tracking branches are merged.

       merge.ff
	   By default, Git does not create an extra merge commit when merging a commit that is a
	   descendant of the current commit. Instead, the tip of the current branch is
	   fast-forwarded. When set to false, this variable tells Git to create an extra merge
	   commit in such a case (equivalent to giving the --no-ff option from the command line).
	   When set to only, only such fast-forward merges are allowed (equivalent to giving the
	   --ff-only option from the command line).

       merge.log
	   In addition to branch names, populate the log message with at most the specified
	   number of one-line descriptions from the actual commits that are being merged.
	   Defaults to false, and true is a synonym for 20.

       merge.renameLimit
	   The number of files to consider when performing rename detection during a merge; if
	   not specified, defaults to the value of diff.renameLimit.

       merge.renormalize
	   Tell Git that canonical representation of files in the repository has changed over
	   time (e.g. earlier commits record text files with CRLF line endings, but recent ones
	   use LF line endings). In such a repository, Git can convert the data recorded in
	   commits to a canonical form before performing a merge to reduce unnecessary conflicts.
	   For more information, see section "Merging branches with differing checkin/checkout
	   attributes" in gitattributes(5).

       merge.stat
	   Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the
	   merge. True by default.

       merge.tool
	   Controls which merge tool is used by git-mergetool(1). The list below shows the valid
	   built-in values. Any other value is treated as a custom merge tool and requires that a
	   corresponding mergetool.<tool>.cmd variable is defined.

	   o   araxis

	   o   bc3

	   o   codecompare

	   o   deltawalker

	   o   diffuse

	   o   ecmerge

	   o   emerge

	   o   gvimdiff

	   o   gvimdiff2

	   o   kdiff3

	   o   meld

	   o   opendiff

	   o   p4merge

	   o   tkdiff

	   o   tortoisemerge

	   o   vimdiff

	   o   vimdiff2

	   o   xxdiff

       merge.verbosity
	   Controls the amount of output shown by the recursive merge strategy. Level 0 outputs
	   nothing except a final error message if conflicts were detected. Level 1 outputs only
	   conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging
	   information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY
	   environment variable.

       merge.<driver>.name
	   Defines a human-readable name for a custom low-level merge driver. See
	   gitattributes(5) for details.

       merge.<driver>.driver
	   Defines the command that implements a custom low-level merge driver. See
	   gitattributes(5) for details.

       merge.<driver>.recursive
	   Names a low-level merge driver to be used when performing an internal merge between
	   common ancestors. See gitattributes(5) for details.

       mergetool.<tool>.path
	   Override the path for the given tool. This is useful in case your tool is not in the
	   PATH.

       mergetool.<tool>.cmd
	   Specify the command to invoke the specified merge tool. The specified command is
	   evaluated in shell with the following variables available: BASE is the name of a
	   temporary file containing the common base of the files to be merged, if available;
	   LOCAL is the name of a temporary file containing the contents of the file on the
	   current branch; REMOTE is the name of a temporary file containing the contents of the
	   file from the branch being merged; MERGED contains the name of the file to which the
	   merge tool should write the results of a successful merge.

       mergetool.<tool>.trustExitCode
	   For a custom merge command, specify whether the exit code of the merge command can be
	   used to determine whether the merge was successful. If this is not set to true then
	   the merge target file timestamp is checked and the merge assumed to have been
	   successful if the file has been updated, otherwise the user is prompted to indicate
	   the success of the merge.

       mergetool.keepBackup
	   After performing a merge, the original file with conflict markers can be saved as a
	   file with a .orig extension. If this variable is set to false then this file is not
	   preserved. Defaults to true (i.e. keep the backup files).

       mergetool.keepTemporaries
	   When invoking a custom merge tool, Git uses a set of temporary files to pass to the
	   tool. If the tool returns an error and this variable is set to true, then these
	   temporary files will be preserved, otherwise they will be removed after the tool has
	   exited. Defaults to false.

       mergetool.prompt
	   Prompt before each invocation of the merge resolution program.

       notes.displayRef
	   The (fully qualified) refname from which to show notes when showing commit messages.
	   The value of this variable can be set to a glob, in which case notes from all matching
	   refs will be shown. You may also specify this configuration variable several times. A
	   warning will be issued for refs that do not exist, but a glob that does not match any
	   refs is silently ignored.

	   This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable,
	   which must be a colon separated list of refs or globs.

	   The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also
	   implicitly added to the list of refs to be displayed.

       notes.rewrite.<command>
	   When rewriting commits with <command> (currently amend or rebase) and this variable is
	   set to true, Git automatically copies your notes from the original to the rewritten
	   commit. Defaults to true, but see "notes.rewriteRef" below.

       notes.rewriteMode
	   When copying notes during a rewrite (see the "notes.rewrite.<command>" option),
	   determines what to do if the target commit already has a note. Must be one of
	   overwrite, concatenate, or ignore. Defaults to concatenate.

	   This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

       notes.rewriteRef
	   When copying notes during a rewrite, specifies the (fully qualified) ref whose notes
	   should be copied. The ref may be a glob, in which case notes in all matching refs will
	   be copied. You may also specify this configuration several times.

	   Does not have a default value; you must configure this variable to enable note
	   rewriting. Set it to refs/notes/commits to enable rewriting for the default commit
	   notes.

	   This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable,
	   which must be a colon separated list of refs or globs.

       pack.window
	   The size of the window used by git-pack-objects(1) when no window size is given on the
	   command line. Defaults to 10.

       pack.depth
	   The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on
	   the command line. Defaults to 50.

       pack.windowMemory
	   The window memory size limit used by git-pack-objects(1) when no limit is given on the
	   command line. The value can be suffixed with "k", "m", or "g". Defaults to 0, meaning
	   no limit.

       pack.compression
	   An integer -1..9, indicating the compression level for objects in a pack file. -1 is
	   the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9
	   being slowest. If not set, defaults to core.compression. If that is not set, defaults
	   to -1, the zlib default, which is "a default compromise between speed and compression
	   (currently equivalent to level 6)."

	   Note that changing the compression level will not automatically recompress all
	   existing objects. You can force recompression by passing the -F option to git-
	   repack(1).

       pack.deltaCacheSize
	   The maximum memory in bytes used for caching deltas in git-pack-objects(1) before
	   writing them out to a pack. This cache is used to speed up the writing object phase by
	   not having to recompute the final delta result once the best match for all objects is
	   found. Repacking large repositories on machines which are tight with memory might be
	   badly impacted by this though, especially if this cache pushes the system into
	   swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to
	   virtually disable this cache. Defaults to 256 MiB.

       pack.deltaCacheLimit
	   The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used
	   to speed up the writing object phase by not having to recompute the final delta result
	   once the best match for all objects is found. Defaults to 1000.

       pack.threads
	   Specifies the number of threads to spawn when searching for best delta matches. This
	   requires that git-pack-objects(1) be compiled with pthreads otherwise this option is
	   ignored with a warning. This is meant to reduce packing time on multiprocessor
	   machines. The required amount of memory for the delta search window is however
	   multiplied by the number of threads. Specifying 0 will cause Git to auto-detect the
	   number of CPU's and set the number of threads accordingly.

       pack.indexVersion
	   Specify the default pack index version. Valid values are 1 for legacy pack index used
	   by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for
	   packs larger than 4 GB as well as proper protection against the repacking of corrupted
	   packs. Version 2 is the default. Note that version 2 is enforced and this config
	   option ignored whenever the corresponding pack is larger than 2 GB.

	   If you have an old Git that does not understand the version 2 *.idx file, cloning or
	   fetching over a non native protocol (e.g. "http" and "rsync") that will copy both
	   *.pack file and corresponding *.idx file from the other side may give you a repository
	   that cannot be accessed with your older version of Git. If the *.pack file is smaller
	   than 2 GB, however, you can use git-index-pack(1) on the *.pack file to regenerate the
	   *.idx file.

       pack.packSizeLimit
	   The maximum size of a pack. This setting only affects packing to a file when
	   repacking, i.e. the git:// protocol is unaffected. It can be overridden by the
	   --max-pack-size option of git-repack(1). The minimum size allowed is limited to 1 MiB.
	   The default is unlimited. Common unit suffixes of k, m, or g are supported.

       pager.<cmd>
	   If the value is boolean, turns on or off pagination of the output of a particular Git
	   subcommand when writing to a tty. Otherwise, turns on pagination for the subcommand
	   using the pager specified by the value of pager.<cmd>. If --paginate or --no-pager is
	   specified on the command line, it takes precedence over this option. To disable
	   pagination for all commands, set core.pager or GIT_PAGER to cat.

       pretty.<name>
	   Alias for a --pretty= format string, as specified in git-log(1). Any aliases defined
	   here can be used just as the built-in pretty formats could. For example, running git
	   config pretty.changelog "format:* %H %s" would cause the invocation git log
	   --pretty=changelog to be equivalent to running git log "--pretty=format:* %H %s". Note
	   that an alias with the same name as a built-in format will be silently ignored.

       pull.rebase
	   When true, rebase branches on top of the fetched branch, instead of merging the
	   default branch from the default remote when "git pull" is run. See
	   "branch.<name>.rebase" for setting this on a per-branch basis.

	   NOTE: this is a possibly dangerous operation; do not use it unless you understand the
	   implications (see git-rebase(1) for details).

       pull.octopus
	   The default merge strategy to use when pulling multiple branches at once.

       pull.twohead
	   The default merge strategy to use when pulling a single branch.

       push.default
	   Defines the action git push should take if no refspec is given on the command line, no
	   refspec is configured in the remote, and no refspec is implied by any of the options
	   given on the command line. Possible values are:

	   o   nothing - do not push anything.

	   o   matching - push all branches having the same name in both ends. This is for those
	       who prepare all the branches into a publishable shape and then push them out with
	       a single command. It is not appropriate for pushing into a repository shared by
	       multiple users, since locally stalled branches will attempt a non-fast forward
	       push if other users updated the branch.

	       This is currently the default, but Git 2.0 will change the default to simple.

	   o   upstream - push the current branch to its upstream branch (tracking is a
	       deprecated synonym for this). With this, git push will update the same remote ref
	       as the one which is merged by git pull, making push and pull symmetrical. See
	       "branch.<name>.merge" for how to configure the upstream branch.

	   o   simple - like upstream, but refuses to push if the upstream branch's name is
	       different from the local one. This is the safest option and is well-suited for
	       beginners. It will become the default in Git 2.0.

	   o   current - push the current branch to a branch of the same name.

	   The simple, current and upstream modes are for those who want to push out a single
	   branch after finishing work, even when the other branches are not yet ready to be
	   pushed out. If you are working with other people to push into the same shared
	   repository, you would want to use one of these.

       rebase.stat
	   Whether to show a diffstat of what changed upstream since the last rebase. False by
	   default.

       rebase.autosquash
	   If set to true enable --autosquash option by default.

       receive.autogc
	   By default, git-receive-pack will run "git-gc --auto" after receiving data from
	   git-push and updating refs. You can stop it by setting this variable to false.

       receive.fsckObjects
	   If it is set to true, git-receive-pack will check all received objects. It will abort
	   in the case of a malformed object or a broken link. The result of an abort are only
	   dangling objects. Defaults to false. If not set, the value of transfer.fsckObjects is
	   used instead.

       receive.unpackLimit
	   If the number of objects received in a push is below this limit then the objects will
	   be unpacked into loose object files. However if the number of received objects equals
	   or exceeds this limit then the received pack will be stored as a pack, after adding
	   any missing delta bases. Storing the pack from a push can make the push operation
	   complete faster, especially on slow filesystems. If not set, the value of
	   transfer.unpackLimit is used instead.

       receive.denyDeletes
	   If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this
	   to prevent such a ref deletion via a push.

       receive.denyDeleteCurrent
	   If set to true, git-receive-pack will deny a ref update that deletes the currently
	   checked out branch of a non-bare repository.

       receive.denyCurrentBranch
	   If set to true or "refuse", git-receive-pack will deny a ref update to the currently
	   checked out branch of a non-bare repository. Such a push is potentially dangerous
	   because it brings the HEAD out of sync with the index and working tree. If set to
	   "warn", print a warning of such a push to stderr, but allow the push to proceed. If
	   set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

       receive.denyNonFastForwards
	   If set to true, git-receive-pack will deny a ref update which is not a fast-forward.
	   Use this to prevent such an update via a push, even if that push is forced. This
	   configuration variable is set when initializing a shared repository.

       receive.hiderefs
	   String(s) receive-pack uses to decide which refs to omit from its initial
	   advertisement. Use more than one definitions to specify multiple prefix strings. A ref
	   that are under the hierarchies listed on the value of this variable is excluded, and
	   is hidden when responding to git push, and an attempt to update or delete a hidden ref
	   by git push is rejected.

       receive.updateserverinfo
	   If set to true, git-receive-pack will run git-update-server-info after receiving data
	   from git-push and updating refs.

       remote.pushdefault
	   The remote to push to by default. Overrides branch.<name>.remote for all branches, and
	   is overridden by branch.<name>.pushremote for specific branches.

       remote.<name>.url
	   The URL of a remote repository. See git-fetch(1) or git-push(1).

       remote.<name>.pushurl
	   The push URL of a remote repository. See git-push(1).

       remote.<name>.proxy
	   For remotes that require curl (http, https and ftp), the URL to the proxy to use for
	   that remote. Set to the empty string to disable proxying for that remote.

       remote.<name>.fetch
	   The default set of "refspec" for git-fetch(1). See git-fetch(1).

       remote.<name>.push
	   The default set of "refspec" for git-push(1). See git-push(1).

       remote.<name>.mirror
	   If true, pushing to this remote will automatically behave as if the --mirror option
	   was given on the command line.

       remote.<name>.skipDefaultUpdate
	   If true, this remote will be skipped by default when updating using git-fetch(1) or
	   the update subcommand of git-remote(1).

       remote.<name>.skipFetchAll
	   If true, this remote will be skipped by default when updating using git-fetch(1) or
	   the update subcommand of git-remote(1).

       remote.<name>.receivepack
	   The default program to execute on the remote side when pushing. See option
	   --receive-pack of git-push(1).

       remote.<name>.uploadpack
	   The default program to execute on the remote side when fetching. See option
	   --upload-pack of git-fetch-pack(1).

       remote.<name>.tagopt
	   Setting this value to --no-tags disables automatic tag following when fetching from
	   remote <name>. Setting it to --tags will fetch every tag from remote <name>, even if
	   they are not reachable from remote branch heads. Passing these flags directly to git-
	   fetch(1) can override this setting. See options --tags and --no-tags of git-fetch(1).

       remote.<name>.vcs
	   Setting this to a value <vcs> will cause Git to interact with the remote with the
	   git-remote-<vcs> helper.

       remotes.<group>
	   The list of remotes which are fetched by "git remote update <group>". See git-
	   remote(1).

       repack.usedeltabaseoffset
	   By default, git-repack(1) creates packs that use delta-base offset. If you need to
	   share your repository with Git older than version 1.4.4, either directly or via a dumb
	   protocol such as http, then you need to set this option to "false" and repack. Access
	   from old Git versions over the native protocol are unaffected by this option.

       rerere.autoupdate
	   When set to true, git-rerere updates the index with the resulting contents after it
	   cleanly resolves conflicts using previously recorded resolution. Defaults to false.

       rerere.enabled
	   Activate recording of resolved conflicts, so that identical conflict hunks can be
	   resolved automatically, should they be encountered again. By default, git-rerere(1) is
	   enabled if there is an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was
	   previously used in the repository.

       sendemail.identity
	   A configuration identity. When given, causes values in the sendemail.<identity>
	   subsection to take precedence over values in the sendemail section. The default
	   identity is the value of sendemail.identity.

       sendemail.smtpencryption
	   See git-send-email(1) for description. Note that this setting is not subject to the
	   identity mechanism.

       sendemail.smtpssl
	   Deprecated alias for sendemail.smtpencryption = ssl.

       sendemail.<identity>.*
	   Identity-specific versions of the sendemail.*  parameters found below, taking
	   precedence over those when the this identity is selected, through command-line or
	   sendemail.identity.

       sendemail.aliasesfile, sendemail.aliasfiletype, sendemail.annotate, sendemail.bcc,
       sendemail.cc, sendemail.cccmd, sendemail.chainreplyto, sendemail.confirm,
       sendemail.envelopesender, sendemail.from, sendemail.multiedit, sendemail.signedoffbycc,
       sendemail.smtppass, sendemail.suppresscc, sendemail.suppressfrom, sendemail.to,
       sendemail.smtpdomain, sendemail.smtpserver, sendemail.smtpserverport,
       sendemail.smtpserveroption, sendemail.smtpuser, sendemail.thread, sendemail.validate
	   See git-send-email(1) for description.

       sendemail.signedoffcc
	   Deprecated alias for sendemail.signedoffbycc.

       showbranch.default
	   The default set of branches for git-show-branch(1). See git-show-branch(1).

       status.relativePaths
	   By default, git-status(1) shows paths relative to the current directory. Setting this
	   variable to false shows paths relative to the repository root (this was the default
	   for Git prior to v1.5.4).

       status.showUntrackedFiles
	   By default, git-status(1) and git-commit(1) show files which are not currently tracked
	   by Git. Directories which contain only untracked files, are shown with the directory
	   name only. Showing untracked files means that Git needs to lstat() all all the files
	   in the whole repository, which might be slow on some systems. So, this variable
	   controls how the commands displays the untracked files. Possible values are:

	   o   no - Show no untracked files.

	   o   normal - Show untracked files and directories.

	   o   all - Show also individual files in untracked directories.

	   If this variable is not specified, it defaults to normal. This variable can be
	   overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

       status.submodulesummary
	   Defaults to false. If this is set to a non zero number or true (identical to -1 or an
	   unlimited number), the submodule summary will be enabled and a summary of commits for
	   modified submodules will be shown (see --summary-limit option of git-submodule(1)).

       submodule.<name>.path, submodule.<name>.url, submodule.<name>.update
	   The path within this project, URL, and the updating strategy for a submodule. These
	   variables are initially populated by git submodule init; edit them to override the URL
	   and other values found in the .gitmodules file. See git-submodule(1) and gitmodules(5)
	   for details.

       submodule.<name>.branch
	   The remote branch name for a submodule, used by git submodule update --remote. Set
	   this option to override the value found in the .gitmodules file. See git-submodule(1)
	   and gitmodules(5) for details.

       submodule.<name>.fetchRecurseSubmodules
	   This option can be used to control recursive fetching of this submodule. It can be
	   overridden by using the --[no-]recurse-submodules command line option to "git fetch"
	   and "git pull". This setting will override that from in the gitmodules(5) file.

       submodule.<name>.ignore
	   Defines under what circumstances "git status" and the diff family show a submodule as
	   modified. When set to "all", it will never be considered modified, "dirty" will ignore
	   all changes to the submodules work tree and takes only differences between the HEAD of
	   the submodule and the commit recorded in the superproject into account. "untracked"
	   will additionally let submodules with modified tracked files in their work tree show
	   up. Using "none" (the default when this option is not set) also shows submodules that
	   have untracked files in their work tree as changed. This setting overrides any setting
	   made in .gitmodules for this submodule, both settings can be overridden on the command
	   line by using the "--ignore-submodules" option.

       tar.umask
	   This variable can be used to restrict the permission bits of tar archive entries. The
	   default is 0002, which turns off the world write bit. The special value "user"
	   indicates that the archiving user's umask will be used instead. See umask(2) and git-
	   archive(1).

       transfer.fsckObjects
	   When fetch.fsckObjects or receive.fsckObjects are not set, the value of this variable
	   is used instead. Defaults to false.

       transfer.hiderefs
	   This variable can be used to set both receive.hiderefs and uploadpack.hiderefs at the
	   same time to the same values. See entries for these other variables.

       transfer.unpackLimit
	   When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable
	   is used instead. The default value is 100.

       uploadpack.hiderefs
	   String(s) upload-pack uses to decide which refs to omit from its initial
	   advertisement. Use more than one definitions to specify multiple prefix strings. A ref
	   that are under the hierarchies listed on the value of this variable is excluded, and
	   is hidden from git ls-remote, git fetch, etc. An attempt to fetch a hidden ref by git
	   fetch will fail. See also uploadpack.allowtipsha1inwant.

       uploadpack.allowtipsha1inwant
	   When uploadpack.hiderefs is in effect, allow upload-pack to accept a fetch request
	   that asks for an object at the tip of a hidden ref (by default, such a request is
	   rejected). see also uploadpack.hiderefs.

       url.<base>.insteadOf
	   Any URL that starts with this value will be rewritten to start, instead, with <base>.
	   In cases where some site serves a large number of repositories, and serves them with
	   multiple access methods, and some users need to use different access methods, this
	   feature allows people to specify any of the equivalent URLs and have Git automatically
	   rewrite the URL to the best alternative for the particular user, even for a
	   never-before-seen repository on the site. When more than one insteadOf strings match a
	   given URL, the longest match is used.

       url.<base>.pushInsteadOf
	   Any URL that starts with this value will not be pushed to; instead, it will be
	   rewritten to start with <base>, and the resulting URL will be pushed to. In cases
	   where some site serves a large number of repositories, and serves them with multiple
	   access methods, some of which do not allow push, this feature allows people to specify
	   a pull-only URL and have Git automatically use an appropriate URL to push, even for a
	   never-before-seen repository on the site. When more than one pushInsteadOf strings
	   match a given URL, the longest match is used. If a remote has an explicit pushurl, Git
	   will ignore this setting for that remote.

       user.email
	   Your email address to be recorded in any newly created commits. Can be overridden by
	   the GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and EMAIL environment variables. See git-
	   commit-tree(1).

       user.name
	   Your full name to be recorded in any newly created commits. Can be overridden by the
	   GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See git-commit-tree(1).

       user.signingkey
	   If git-tag(1) is not selecting the key you want it to automatically when creating a
	   signed tag, you can override the default selection with this variable. This option is
	   passed unchanged to gpg's --local-user parameter, so you may specify a key using any
	   method that gpg supports.

       web.browser
	   Specify a web browser that may be used by some commands. Currently only git-
	   instaweb(1) and git-help(1) may use it.
