+NAME
+----
+git-ls-tree - List the contents of a tree object
+
+
+SYNOPSIS
+--------
+[verse]
+'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:
+
+ - 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+	\0 line termination on output and do not quote filenames.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.
+
+--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>
+
+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.
+
+Without the `-z` option, pathnames with "unusual" characters are
+quoted as explained for the configuration variable `core.quotePath`
+(see linkgit:git-config[1]).  Using `-z` the filename is output
+verbatim and the line is terminated by a NUL byte.
