I'm aware that branches don't really store creator information - and they're just a pointer to a commit.
My goal is to be able to clean out my old branches that have been merged back to the main branch, and list branches where this hasn't been done either. (A clean up).
This is different to "finding unmerged branches" because I want to find merged branches as well, and I want to do it by author.
My question is: Is there a script to list git branches created by me?
This command lists all branches and their author names
git for-each-ref --format=' %(authorname) %09 %(refname)' --sort=authorname
If you are using github you can also visit https://github.com/author/repo/branches/yours to get all your branches
If you want to just delete all the already merged branches you can us the command
git branch --merged | grep -v "\*" | grep -v master | grep -v dev | xargs -n 1 git branch -d
