Changing commit logs in git

It sounds like something you shouldn't do, but sometimes you may want to adjust who made a commit. Maybe you did a commit on a vagrant box or maybe you fat fingered your name or email address while typing too fast. To change the committer I found this handy

#!/bin/sh
 
git filter-branch --env-filter '

OLD_EMAIL="bad@emailaddress"
CORRECT_NAME="Russell Simpkins"
CORRECT_EMAIL="russellsimpkins@real-domain"

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

Simply adjust the OLD_EMAIL, CORRECT_NAME and CORRECT_EMAIL and stuff that into a bash script. Then issue a git push --force
