git-prune - Man Page

• Simulate pruning, reporting what would be removed: git prune [-n|--dry-run]
• Prune unreachable objects and display what has been pruned to stdout: git prune [-v|--verbose]
• Prune unreachable objects while showing progress: git prune --progress

tldr.sh

git prune [-n] [-v] [--progress] [--expire <time>] [--] [<head>​...]

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 git-repack(1)​.

-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​.

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)

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​.
