NAME
       git-prune - Prune all unreachable objects from the object database


SYNOPSIS
       git prune [-n] [-v] [--expire <expire>] [--] [<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
       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 git-
       repack(1).


OPTIONS
       -n, --dry-run
           Do not remove anything; just report what it would remove.

       -v, --verbose
           Report all removed objects.

       --
           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 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.
