DESCRIPTION
-----------
-Converts the tree object to a human readable (and script processable)

+Lists the contents of a tree object, like what "/bin/ls -a" does

OPTIONS
-------
<tree-ish>::
Id of a tree.
+-d::

+
-r::
recurse into sub-trees

\0 line termination on output
paths::
- Optionally, restrict the output of git-ls-tree to specific
- paths. Directories will only list their tree blob ids.
- Implies -r.
+ When paths are given, shows them. Otherwise implicitly
+ uses the root level of the tree as the sole path argument.

- Get all the objects.
--d::
- Do not check for delta base objects (use this option

---recover::
- Check dependency of deltified object more carefully than
- usual, to recover after earlier pull that was interrupted.

NAME
----
-git-ls-tree - Displays a tree object in human readable form
+git-ls-tree - Lists the contents of a tree object.
SYNOPSIS
--------
-'git-ls-tree' [-r] [-z] <tree-ish> [paths...]
+'git-ls-tree' [-d] [-r] [-z] <tree-ish> [paths...]
DESCRIPTION
-----------
-Converts the tree object to a human readable (and script processable)
-form.
+Lists the contents of a tree object, like what "/bin/ls -a" does
+in the current working directory.
OPTIONS
-------
<tree-ish>::
Id of a tree.
+-d::
+ show only the named tree entry itself, not its children
+
-r::
recurse into sub-trees
@@ -28,18 +31,19 @@ OPTIONS
\0 line termination on output
paths::
- Optionally, restrict the output of git-ls-tree to specific
- paths. Directories will only list their tree blob ids.
- Implies -r.
+ When paths are given, shows them. Otherwise implicitly
+ uses the root level of the tree as the sole path argument.
+
Output Format
-------------
- <mode>\t <type>\t <object>\t <file>
+ <mode> SP <type> SP <object> TAB <file>
