# Clean Gone Branches Remove local git branches that have been deleted from the remote. ## Process 1. **Update remote references** - Run `git fetch --prune`. 2. **Inspect local state** - Run `git branch -vv` to find branches marked as `[gone]`. - Run `git worktree list` to see whether any of those branches still have worktrees. 3. **Remove worktrees first** - For each `[gone]` branch that still has a worktree, remove the worktree before deleting the branch. 4. **Delete the gone branches** - Delete each local branch marked as `[gone]`. 5. **Report the result** - List removed worktrees and deleted branches. - If there are no `[gone]` branches, report that nothing needed cleanup.
