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 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.
