SYNOPSIS
--------
'git-ls-tree' [-d] [-r] [-t] [-z] [--name-only] [--name-status] <tree-ish> [paths...]
'git-ls-tree' [-d] [-r] [-t] [-z]
[--name-only] [--name-status] [--full-name] [--abbrev=[<n>]]
<tree-ish> [paths...]
DESCRIPTION
-----------
@ -40,6 +42,11 @@ OPTIONS
--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 handful hexdigits prefix.
Non default number of digits can be specified with --abbrev=<n>.
paths::
When paths are given, show them (note that this isn't really raw
pathnames, but rather a list of patterns to match). Otherwise
