git prune [options]

git prune removes unreachable objects from the object database. Objects become unreachable when their referencing commits are deleted, rebased away, or otherwise orphaned.
The command is typically run as part of `git gc` rather than directly. The `--expire` option prevents pruning recent objects that might still be needed by concurrent operations, providing a safety margin.
