Prune Branches

Your task

Delete every local branch whose upstream is gone, removing any attached worktree first. If nothing is marked [gone], report that and stop.

Steps

1. List branches with verbose status to surface [gone] markers and any + prefix indicating an attached worktree:

   git branch -v
   

2. List worktrees so you know which paths will be removed:

   git worktree list
   

3. Remove worktrees and delete [gone] branches in one pass. Strips the +/*/space prefix, finds the worktree (if any), and force-deletes the branch:

   git branch -v | grep '\[gone\]' | sed 's/^[+* ]//' | awk '{print $1}' | while read branch; do
     echo "Processing branch: $branch"
     worktree=$(git worktree list | grep "\\[$branch\\]" | awk '{print $1}')
     if [ ! -z "$worktree" ] && [ "$worktree" != "$(git rev-parse --show-toplevel)" ]; then
       echo "  Removing worktree: $worktree"
       git worktree remove --force "$worktree"
     fi
     echo "  Deleting branch: $branch"
     git branch -D "$branch"
   done
   

Reporting

• Print which worktrees were removed and which branches were deleted.
• If no [gone] branches exist, say "No cleanup needed" and stop.
• Never delete branches that are not marked [gone].
• Never touch the current working tree's root path.
