git-ls-tree
GIT-LS-TREE(1) Git Manual GIT-LS-TREE(1)
NAME
git-ls-tree - List the contents of a tree object
SYNOPSIS
git ls-tree [-d] [-r] [-t] [-l] [-z]
[--name-only] [--name-status] [--full-name] [--full-tree] [--abbrev[=<n>]]
<tree-ish> [<path>...]
DESCRIPTION
Lists the contents of a given tree object, like what "/bin/ls -a" does in the current working directory. Note that:
o the behaviour is slightly different from that of "/bin/ls" in that the <path> denotes just a list of patterns to match, e.g. so
specifying directory name (without -r) will behave differently, and order of the arguments does not matter.
o the behaviour is similar to that of "/bin/ls" in that the <path> is taken as relative to the current working directory. E.g. when you
are in a directory sub that has a directory dir, you can run git ls-tree -r HEAD dir to list the contents of the tree (that is sub/dir
in HEAD). You don't want to give a tree that is not at the root level (e.g. git ls-tree -r HEAD:sub dir) in this case, as that would
result in asking for sub/sub/dir in the HEAD commit. However, the current working directory can be ignored by passing --full-tree
option.
OPTIONS
<tree-ish>
Id of a tree-ish.
-d
Show only the named tree entry itself, not its children.
-r
Recurse into sub-trees.
-t
Show tree entries even when going to recurse them. Has no effect if -r was not passed. -d implies -t.
-l, --long
Show object size of blob (file) entries.
-z
line termination on output.
--name-only, --name-status
List only filenames (instead of the "long" output), one per line.
--abbrev[=<n>]
Instead of showing the full 40-byte hexadecimal object lines, show only a partial prefix. Non default number of digits can be specified
with --abbrev=<n>.
--full-name
Instead of showing the path names relative to the current working directory, show the full path names.
--full-tree
Do not limit the listing to the current working directory. Implies --full-name.
[<path>...]
When paths are given, show them (note that this isn't really raw pathnames, but rather a list of patterns to match). Otherwise
implicitly uses the root level of the tree as the sole path argument.
OUTPUT FORMAT
<mode> SP <type> SP <object> TAB <file>
Unless the -z option is used, TAB, LF, and backslash characters in pathnames are represented as ,
, and \, respectively. This output
format is compatible with what --index-info --stdin of git update-index expects.
When the -l option is used, format changes to
<mode> SP <type> SP <object> SP <object size> TAB <file>
Object size identified by <object> is given in bytes, and right-justified with minimum width of 7 characters. Object size is given only for
blobs (file) entries; for other entries - character is used in place of size.
