Git: How do I list local branches that are tracking remote branches that no longer exist?

Question

How can I list any local branches that appear (as per .git/config) to be tracking remote branches that no longer exist? Remote branches are on GitHub in this ca

Answer 1

To list your local branches which track deleted remote branches you can use git remote prune --dry-run

For example (assuming your remote repository is named origin):

git fetch
git remote prune origin --dry-run

You can remove the --dry-run option to delete the branches from your local repository
