Tired of cleaning out your merged Gerrit branches by hand? Freaked out when git tells you your branches aren't fully merged yet (but it's actually fine because it changed SHA1 at rebase time)? Just run `gerrit-clean` in your repository and it will delete branches that have been merged into your master.

gistfile1.sh

function gerrit-clean () {
    for branch in $(git for-each-ref --format='%(refname:short)' refs/heads/); do
        if git log master|ack -1 "$(git log "$branch"|ack -1 Change-Id)" > /dev/null; then
            if [ "$branch" != "master" ]; then
                git branch -D "$branch"
            fi
        fi
    done
}
