GIT-PRUNE(1)                      Git Manual                      GIT-PRUNE(1)

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 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.
