I have separate emails for personal use and office use, so as my Git accounts. I use a small script to update my git config when I have to change workspace. But sometime I forget to do so (most of the time actually). So I end up making commit with wrong git account.
While search for solutions to fix this I found this awesome script, from Github, that could change author email and name of existing commits. How cool is that!
So, I decided to keep it here :)
#!/bin/sh git filter-branch --env-filter ' OLD_EMAIL="firstname.lastname@example.org" CORRECT_NAME="Your Correct Name" CORRECT_EMAIL="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
CORRECT_EMAIL as necessary. Just save it in a
.sh file and run it. Thats it.
There is a chance that you might get a error like this:
Cannot create a new backup. A previous backup already exists in refs/original/ Force overwriting the backup with -f
In which case you have to remove the
rm -rf .git/refs/original
git logs . And finally push them to repo:
git push --force --tags origin 'refs/heads/*'
