Hello,

I've got a few private repos that I am the sole contributor to, but some
commits are under my usual Git author+email. These commits are
automated, and I'd like to rewrite commits that match the commit message
(the message is consistent) and the 'old' author+email to a new
author+email, but retain the commit message.

The tool that springs to mind is `git-filter-branch`. However, I've also
come across `git-filter-repo` on GitHub.

I'm a little confused, and I wanted to ask for advice on the list. I did
try using `git-filter-branch`, but got lost quickly with
`--commit-filter/`--msg-filter`.

I also found a 'users' Git mailing list on Google Groups, but by the
warning I got from Google, it has a spam issue. If this is the wrong
place to ask for help, please do let me know.

Thank you.

Best wishes,

git-filter-repo(1) is better—even `man git-filter-branch` recommends it.

Yes.  That place is dead.  Avoid it.

Or it was when I looked at it back in February.
