Git prune is a command used to remove unreachable objects from the Git database. When you delete a branch or commit, the objects associated with them remain in the database as long as they are still referenced by other objects. However, if there are no references to these objects, they become unreachable and can be safely deleted using git prune.
The command syntax for git prune is:
git prune [<options>] [<commit>…]
Here are some of the options you can use with git prune:
--verbose: Shows detailed output about which objects were pruned.--dry-run: Displays what would be pruned without actually deleting anything.--expire=<time>: Specifies how long (in days) Git should wait before pruning loose objects that are not reachable by any reference.
It’s important to note that git prune only removes unreferenced objects from your local repository. If you want to remove these objects from a remote repository, you’ll need to run git gc on that repository.
