Objects that already exist in the repository will not be unpacked from the pack-file. Therefore, nothing will be unpacked if you use this command on a pack-file that exists within the target repository.

Please see the git-repack documentation for options to generate new packs and replace existing ones.

-n

Only list the objects that would be unpacked, don't actually unpack them.

-q

The command usually shows percentage progress. This flag suppresses it.

-r

When unpacking a corrupt packfile, the command dies at the first corruption. This flag tells it to keep going and make the best effort to recover as many objects as possible.
