How to list and delete branches

List branches

# list your local branches
$ git branch

# list your remote branches
$ git branch -r

# list both remote and local branches
$ git branch -a

See the last commit on each Branch

$ git branch -v

List merged or not merged branches

# list the branches that are already merged into the branch you're on
$ git branch --merged

# list the branches that contain work you haven't yet merged in
$ git branch --no-merged

Delete branches

# delete a local branch
$ git branch -d <>

# delete a remote branch
$ git push origin :<>

If you have other branches that contain work that haven’t merged in yet, trying to delete it with git branch -d will fail.
But if you really do want to delete the branch and lose that work, you can force it with -D.

# force to delete an unmerged branch
$ git branch -D <>
