NAME

-git-prune - Prunes all unreachable objects from the object database
+git-prune - Prune all unreachable objects from the object database
SYNOPSIS
--------
-'git-prune' [-n]
+'git-prune' [-n] [--expire <expire>] [--] [<head>...]
DESCRIPTION
-----------
-This runs `git-fsck-objects --unreachable` using the heads
-specified on the command line (or `$GIT_DIR/refs/heads/\*` and
-`$GIT_DIR/refs/tags/\*` if none is specified), and prunes all
-unreachable objects from the object database. In addition, it
+NOTE: In most cases, users should run linkgit:git-gc[1], which calls
+git-prune. See the section "NOTES", below.
+
+This runs `git-fsck --unreachable` using all the refs
+available in `$GIT_DIR/refs`, optionally with additional set of
+objects specified on the command line, and prunes all unpacked
+objects unreachable from any of these head objects from the object database.
+In addition, it
prunes the unpacked objects that are also found in packs by
running `git prune-packed`.
+Note that unreachable, packed objects will remain. If this is
+not desired, see linkgit:git-repack[1].
+
OPTIONS
-------
Do not remove anything; just report what it would
remove.
+\--::
+ Do not interpret any more arguments as options.
+
+\--expire <time>::
+ Only expire loose objects older than <time>.
+
+<head>...::
+ In addition to objects
+ reachable from any of our references, keep objects
+ reachable from listed <head>s.
+
+EXAMPLE
+-------
+
+To prune objects not used by your repository nor another that
+borrows from your repository via its
+`.git/objects/info/alternates`:
+
+------------
+$ git prune $(cd ../another && $(git-rev-parse --all))
+------------
+
+Notes
+-----
+
+In most cases, users will not need to call git-prune directly, but
+should instead call linkgit:git-gc[1], which handles pruning along with
+many other housekeeping tasks.
+
+For a description of which objects are considered for pruning, see
+git-fsck's --unreachable option.
