Changing author info

Changing the Git history of your repository using a script

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.

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

1. Open TerminalTerminalGit Bash.

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

   git clone --bare https://hostname/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="your-old-email@example.com"
   CORRECT_NAME="Your Correct Name"
   CORRECT_EMAIL="your-correct-email@example.com"
   
   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 Enterprise:

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

7. Clean up the temporary clone:

   cd ..
   rm -rf repo.git
