GIT-PRUNE(1) Git Manual GIT-PRUNE(1)
NAME git-prune - Prune all unreachable objects from the object database
SYNOPSIS 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 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.
--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
