Thanks for keeping me honest. I just read the first line of the stackoverflow, but the one liner is still in the comments. I just tested it.

    git fetch -p && git branch -vv | awk '/: gone]/{print $1}' | xargs git branch -d

That looks fine and will generally work, except when the current branch is one of the ones to be deleted.

The script in OP handles that edge case by switching to the main branch before deleting. That may or may not be intuitive but I think it's a reasonable response. The script also prints error messages for various other bad inputs. Once you strip all that out it's only a few lines long.

I'm going to assume you have about as many years of experience as me based on your profile, but if you're going to argue that maintaining this script - for the sole convenience of deleting a branch out from underneath you - is worth it, then there's nothing more I can do to help you.

Same as mine. I also pass the `-r` flag to xargs so it doesn't run if there are no inputs.
