Update old authors.md

Open Git Bash.

Create a fresh, bare clone of your repository:

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

Then, see which authors have committed to your repo

git shortlog -e -s -n

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

Press Enter to run the script. Review the new Git history for errors. Push the corrected history to GitHub:

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

Clean up the temporary clone:

cd ..
rm -rf repo.git
