Git Branch Cleanup

How to clean up merged branches

Start in your main working copy.

Find merged branches

Have the branch checked out that you want to treat as canonical. The -a option lists all remote branches even if you haven't checked them out locally.

git checkout develop
git branch -a --merged

also, for reference: git branch -a --no-merged

Delete merged branches locally

git branch -d branch-name

Delete merged branches at remote

git push origin :branch-name

Now, in other checkouts of the same repo:

Remove local branches that no longer exist in remote.

git fetch origin
git remote prune origin --dry-run
git remote prune origin
