Warning: This action is destructive to your repository's history. If you're collaborating on a repository with others, it's considered bad practice to rewrite published history. You should only do this in an emergency.
We've created a script that will change any commits that previously had the old email address in its author or committer fields to use the correct name and email address.
Note: Running this script rewrites history for all repository collaborators. After completing these steps, any person with forks or clones must fetch the rewritten history and rebase any local changes into the rewritten history.
Before running this script, you'll need:
- The old email address that appears in the author/committer fields that you want to change
- The correct name and email address that you would like such commits to be attributed to
Open TerminalTerminalGit Bash.
Create a fresh, bare clone of your repository:
git clone --bare https://hostname/user/repo.git cd repo.git
Copy and paste the script, replacing the following variables based on the information you gathered:
#!/bin/sh git filter-branch --env-filter ' OLD_EMAIL="email@example.com" CORRECT_NAME="Your Correct Name" CORRECT_EMAIL="firstname.lastname@example.org" if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ] then export GIT_COMMITTER_NAME="$CORRECT_NAME" export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL" fi if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ] then export GIT_AUTHOR_NAME="$CORRECT_NAME" export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL" fi ' --tag-name-filter cat -- --branches --tags
Press Enter to run the script.
Review the new Git history for errors.
Push the corrected history to GitHub Enterprise:
git push --force --tags origin 'refs/heads/*'
Clean up the temporary clone:
cd .. rm -rf repo.git
