Question

My normal pattern is to branch from master, do a ton of work, then rebase and git svn dcommit. How can I clean up all my old branches?

Basically I want to find any branches that have git-svn-id: in the message and git branch -D those.

NOTE: git branch --no-color --no-track --merged gets me most of the way, but if I ever get into a situation where I need a git fetch -f (because of a crazy git-svn bug) I would have to go and rebase all the branches myself.

Answer 1

A sort-of-one-liner:

git for-each-ref --format='%(refname:short)' refs/heads |
while read branch; do
    if git show -s $branch | grep 'git-svn-id:'; then
        git branch -D $branch
    fi
done

Note that this is untested; I don’t use git-svn, and it’s just based on the requirements in the second paragraph of your question. You might try it first with an echo in there instead of git branch -D, to make sure the list of branches looks like what you’d expect. I can help refine it as necessary.
