You can add other branches to exclude like master and dev if your workflow has those as a possible ancestor. Usually I branch off of a "sprint-start" tag and master, dev and qa are not ancestors.
First, list all branches that were merged in remote.
git branch --merged
You might see few branches you don't want to remove. we can add few arguments to skip important branches that we don't want to delete like master or a develop. The following command will skip master branch and anything that has dev in it.
git branch --merged| egrep -v "(^\*|master|dev)"
If you want to skip, you can add it to the egrep command like the following. The branch
skip_branch_name will not be deleted.
git branch --merged| egrep -v "(^\*|master|dev|skip_branch_name)"
To delete all local branches that are already merged into the currently checked out branch:
git branch --merged | egrep -v "(^\*|master|dev)" | xargs git branch -d
You can see that master and dev are excluded in case they are an ancestor.
You can delete a merged local branch with:
git branch -d branchname
If it's not merged, use:
git branch -D branchname
To delete it from the remote use:
git push --delete origin branchname git push origin :branchname # for really old git
Once you delete the branch from the remote, you can prune to get rid of remote tracking branches with:
git remote prune origin
or prune individual remote tracking branches, as the other answer suggests, with:
git branch -dr branchname
