NAME
git-sh-setup - Common Git shell script setup code SYNOPSIS
. "$(git --exec-path)/git-sh-setup" DESCRIPTION
This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish scripts and/or are writing new ones. The git sh-setup scriptlet is designed to be sourced (using .) by other shell scripts to set up some variables pointing at the normal Git directories and a few helper shell functions. Before sourcing it, your script should set up a few variables; USAGE (and LONG_USAGE, if any) is used to define message given by usage() shell function. SUBDIRECTORY_OK can be set if the script can run from a subdirectory of the working tree (some commands do not). The scriptlet sets GIT_DIR and GIT_OBJECT_DIRECTORY shell variables, but does not export them to the environment. FUNCTIONS
die exit after emitting the supplied error message to the standard error stream. usage die with the usage message. set_reflog_action Set GIT_REFLOG_ACTION environment to a given string (typically the name of the program) unless it is already set. Whenever the script runs a git command that updates refs, a reflog entry is created using the value of this string to leave the record of what command updated the ref. git_editor runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or EDITOR) on a given file, but error out if no editor is specified and the terminal is dumb. is_bare_repository outputs true or false to the standard output stream to indicate if the repository is a bare repository (i.e. without an associated working tree). cd_to_toplevel runs chdir to the toplevel of the working tree. require_work_tree checks if the current directory is within the working tree of the repository, and otherwise dies. require_work_tree_exists checks if the working tree associated with the repository exists, and otherwise dies. Often done before calling cd_to_toplevel, which is impossible to do if there is no working tree. require_clean_work_tree <action> [<hint>] checks that the working tree and index associated with the repository have no uncommitted changes to tracked files. Otherwise it emits an error message of the form Cannot <action>: <reason>. <hint>, and dies. Example: require_clean_work_tree rebase "Please commit or stash them." get_author_ident_from_commit outputs code for use with eval to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit. create_virtual_base modifies the first file so only lines in common with the second file remain. If there is insufficient common material, then the first file is left empty. The result is suitable as a virtual base input for a 3-way merge. GIT

NAME
git-rm - Remove files from the working tree and from the index SYNOPSIS
git rm [-f | --force] [-n] [-r] [--cached] [--ignore-unmatch] [--quiet] [--] <file>... DESCRIPTION
Remove files from the index, or from the working tree and the index. git rm will not remove a file from just your working directory. (There is no option to remove a file only from the working tree and yet keep it in the index; use /bin/rm if you want to do that.) The files being removed have to be identical to the tip of the branch, and no updates to their contents can be staged in the index, though that default behavior can be overridden with the -f option. When --cached is given, the staged content has to match either the tip of the branch or the file on disk, allowing the file to be removed from just the index. OPTIONS
<file>... Files to remove. Fileglobs (e.g. *.c) can be given to remove all matching files. If you want Git to expand file glob characters, you may need to shell-escape them. A leading directory name (e.g. dir to remove dir/file1 and dir/file2) can be given to remove all files in the directory, and recursively all sub-directories, but this requires the -r option to be explicitly given. -f, --force Override the up-to-date check. -n, --dry-run Don't actually remove any file(s). Instead, just show if they exist in the index and would otherwise be removed by the command. -r Allow recursive removal when a leading directory name is given. -- This option can be used to separate command-line options from the list of files, (useful when filenames might be mistaken for command-line options). --cached Use this option to unstage and remove paths only from the index. Working tree files, whether modified or not, will be left alone. --ignore-unmatch Exit with a zero status even if no files matched. -q, --quiet git rm normally outputs one line (in the form of an rm command) for each file removed. This option suppresses that output. DISCUSSION
The <file> list given to the command can be exact pathnames, file glob patterns, or leading directory names. The command removes only the paths that are known to Git. Giving the name of a file that you have not told Git about does not remove that file. File globbing matches across directory boundaries. Thus, given two directories d and d2, there is a difference between using git rm 'd*' and git rm 'd/*', as the former will also remove all of directory d2. REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM
There is no option for git rm to remove from the index only the paths that have disappeared from the filesystem. However, depending on the use case, there are several ways that can be done. Using "git commit -a" If you intend that your next commit should record all modifications of tracked files in the working tree and record all removals of files that have been removed from the working tree with rm (as opposed to git rm), use git commit -a, as it will automatically notice and record all removals. You can also have a similar effect without committing by using git add -u. Using "git add -A" When accepting a new code drop for a vendor branch, you probably want to record both the removal of paths and additions of new paths as well as modifications of existing paths. Typically you would first remove all tracked files from the working tree using this command: git ls-files -z | xargs -0 rm -f and then untar the new code in the working tree. Alternately you could rsync the changes into the working tree. After that, the easiest way to record all removals, additions, and modifications in the working tree is: git add -A See git-add(1). Other ways If all you really want to do is to remove from the index the files that are no longer present in the working tree (perhaps because your working tree is dirty so that you cannot use git commit -a), use the following command: git diff --name-only --diff-filter=D -z | xargs -0 git rm --cached Submodules Only submodules using a gitfile (which means they were cloned with a Git version 1.7.8 or newer) will be removed from the work tree, as their repository lives inside the .git directory of the superproject. If a submodule (or one of those nested inside it) still uses a .git directory, git rm will fail - no matter if forced or not - to protect the submodule's history. A submodule is considered up-to-date when the HEAD is the same as recorded in the index, no tracked files are modified and no untracked files that aren't ignored are present in the submodules work tree. Ignored files are deemed expendable and won't stop a submodule's work tree from being removed. If you only want to remove the local checkout of a submodule from your work tree without committing the removal, use git-submodule(1) deinit instead. EXAMPLES
git rm Documentation/*.txt Removes all *.txt files from the index that are under the Documentation directory and any of its subdirectories. Note that the asterisk * is quoted from the shell in this example; this lets Git, and not the shell, expand the pathnames of files and subdirectories under the Documentation/ directory. git rm -f git-*.sh Because this example lets the shell expand the asterisk (i.e. you are listing the files explicitly), it does not remove subdir/git-foo.sh.
