Bulk edition

  1. Install git-filter-repo which is the official git filter-branch replacement.

  2. Clone repo (bare or not)

$ git clone --bare https://hostname/user/repo.git
$ cd repo.git
  1. Update e-mail and/or name from all commits matching your old@email.com note the usage of bytes)
# update e-mail only
$ git-filter-repo --email-callback 'return email if email != b"old@email.com" else b"username@users.noreply.github.com"'

# update both e-mail and name
$ git-filter-repo --name-callback 'return b"Your Name"' --email-callback ...
  1. Re-add remote repository (git-filter-repo deletes remotes as a safety measure to avoid unintended history rewrites!)
$ git remote add origin <remote-url>
  1. Force push changes (!)
$ git push origin -f --all
