git should come out with a command called `git deadname-killer` that rewrites the history to search/replace commit author name

if anyone has a oneliner for this it would be much appreciated

@SuricrasiaOnline github has a bash script on their site somewhere, but they really should make it easier

@SuricrasiaOnline I once did that kind of thing, but I don't remember the exact command (sorry). Apparently, the help of "git filter-branch" gives an example to change some emails on the whole repo, so you could do the same with the author name.

@SuricrasiaOnline used to have one, not sure where it went though

git filter-repo is probably the more robust solution anyway, it can take a mailmap and rewrite history with it

@SuricrasiaOnline I have corrected deadnames and removed leaked committer & author PII from git multiple times now, but do not have such a one-liner. I have a couple to do now, so it's about time to write a script. There are multiple decisions & gotchas, which become apparent if you look at the names & dates in git log --pretty=fuller and consider the implications of changing every commit hash after the first commit you edit.

I'll post my script & a write-up here when I have it.


with git-filter-repo this should work

git filter-repo --mailmap <(echo "name <email>")

@SuricrasiaOnline write out a .mailmap file and run git-filter-repo (third party) on it to bake in the edits

cool fact: the person who added the .mailmap thing did it expressly for this!

@SuricrasiaOnline every Unix program should also come with a closet-handler so i can manage which names i see based on who’s around

@Lucretia-Matt @SuricrasiaOnline loosely related, when is gitlab going to actually start using the .mailmap file for contributors...?
