reset email multiple commit

I started not to use my real email for git commit. Instead i uses the one that is provided by github

After enabling Block command line pushes that expose my email on Block command line pushes that expose my email, it will reject all email that exposes public email adress.

So in order to rewrite git history and change the author email, I found this github help

#!/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

Another neat way (after you change your email with git config), you can also do this:

$ git rebase -i -p --exec 'git commit --amend --reset-author --no-edit'
