Git-change-history

Changes the author info of ALL past commits. This changes past commit history and forces forked projects to fetch the entire repository. It should only be used as a last resort.

Procedure

1. Open Git Bash.

2. Create a fresh, bare clone of your repository:

   git clone --bare https://github.com/user/repo.git
   cd repo.git

3. Copy and paste the script, replacing the following variables based on the information you gathered:

   • OLD_EMAIL
   • CORRECT_NAME
   • CORRECT_EMAIL

   #!/bin/sh
   
   git filter-branch --env-filter '
   
   OLD_EMAIL="[email protected]"
   CORRECT_NAME="Your Correct Name"
   CORRECT_EMAIL="[email protected]"
   
   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

4. Press Enter to run the script.

5. Review the new Git history for errors.

6. Push the corrected history to GitHub:

   git push --force --tags origin 'refs/heads/*'

7. Clean up the temporary clone:

   cd ..
   rm -rf repo.git
