+NAME
+----
+git-prune - Prune all unreachable objects from the object database
+
+
+SYNOPSIS
+--------
+[verse]
+'git prune' [-n] [-v] [--progress] [--expire <time>] [--] [<head>...]
+
+DESCRIPTION
+-----------
+
+NOTE: In most cases, users should run 'git gc', which calls
+'git prune'. See the section "NOTES", below.
+
+This runs 'git fsck --unreachable' using all the refs
+available in `refs/`, optionally with an 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'.
+It also removes entries from .git/shallow that are not reachable by
+any ref.
+
+Note that unreachable, packed objects will remain.  If this is
+not desired, see linkgit:git-repack[1].
+
+OPTIONS
+-------
+
+-n::
+--dry-run::
+	Do not remove anything; just report what it would
+	remove.
+
+-v::
+--verbose::
+	Report all removed objects.
+
+--progress::
+	Show progress.
+
+--expire <time>::
+	Only expire loose objects older than <time>.
+
+\--::
+	Do not interpret any more arguments as options.
+
+<head>...::
+	In addition to objects
+	reachable from any of our references, keep objects
+	reachable from listed <head>s.
+
+EXAMPLES
+--------
+
+To prune objects not used by your repository or 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 'git gc', 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.
