List the contents of a tree object

Man Page

Name

git-ls-tree - List the contents of a tree object

Synopsis

git ls-tree [-d] [-r] [-t] [-l] [-z]
	    [--name-only] [--name-status] [--object-only] [--full-name] [--full-tree] [--abbrev[=<n>]] [--format=<format>]
	    <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:

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.
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-z: \0 line termination on output and do not quote filenames. See Output FORMAT below for more information.
--name-only
--name-status: List only filenames (instead of the "long" output), one per line. Cannot be combined with --object-only.
--object-only: List only names of the objects, one per line. Cannot be combined with --name-only or --name-status. This is equivalent to specifying --format='%(objectname)', but for both this option and that exact format the command takes a hand-optimized codepath instead of going through the generic formatting mechanism.
--abbrev[=<n>]: Instead of showing the full 40-byte hexadecimal object lines, show the shortest prefix that is at least <n> hexdigits long that uniquely refers the object. 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.
--format=<format>: A string that interpolates %(fieldname) from the result being shown. It also interpolates %% to %, and %xx where xx are hex digits interpolates to character with hex code xx; for example %00 interpolates to \0 (NUL), %09 to \t (TAB) and %0a to \n (LF). When specified, --format cannot be combined with other format-altering options, including --long, --name-only and --object-only.
[<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

The output format of ls-tree is determined by either the --format option, or other format-altering options such as --name-only etc. (see --format above).

The use of certain --format directives is equivalent to using those options, but invoking the full formatting machinery can be slower than using an appropriate formatting option.

In cases where the --format would exactly map to an existing option ls-tree will use the appropriate faster path. Thus the default format is equivalent to:

%(objectmode) %(objecttype) %(objectname)%x09%(path)

This output format is compatible with what --index-info --stdin of git update-index expects.

When the -l option is used, format changes to

%(objectmode) %(objecttype) %(objectname) %(objectsize:padded)%x09%(path)

Object size identified by <objectname> 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.

Without the -z option, pathnames with "unusual" characters are quoted as explained for the configuration variable core.quotePath (see git-config[1]). Using -z the filename is output verbatim and the line is terminated by a NUL byte.

Customized format:

It is possible to print in a custom format by using the --format option, which is able to interpolate different fields using a %(fieldname) notation. For example, if you only care about the "objectname" and "path" fields, you can execute with a specific "--format" like

git ls-tree --format='%(objectname) %(path)' <tree-ish>

FIELD NameS

Various values from structured fields can be used to interpolate into the resulting output. For each outputing line, the following names can be used:

objectmode: The mode of the object.
objecttype: The type of the object (commit, blob or tree).
objectname: The name of the object.
objectsize[:padded]: The size of a blob object ("-" if it’s a commit or tree). It also supports a padded format of size with "%(objectsize:padded)".
path: The pathname of the object.
