git reauthor [options] [range]

git reauthor rewrites commit history to correct author information. It updates author names and email addresses throughout the specified commit range for all commits matching the old email.
The command is useful for fixing incorrect attribution, consolidating identities after email changes, or correcting authorship before publishing a repository. Since it rewrites history, it should only be used on branches that have not been shared.

--old-email EMAIL

Email to match.

New email address.

New author name.

Commit range to process.
