Sometimes I forget to set my email address to my company address for my work projects. This script fixes it. Run before pushing to a remote repo.

git-fix.sh

#!/bin/sh
 
git filter-branch --env-filter '
 
an="$GIT_AUTHOR_NAME"
am="$GIT_AUTHOR_EMAIL"
cn="$GIT_COMMITTER_NAME"
cm="$GIT_COMMITTER_EMAIL"
 
if [ "$GIT_COMMITTER_EMAIL" = "<old_email>" ]
then
    cn="Eric Barendt"
    cm="<new_email>"
fi
if [ "$GIT_AUTHOR_EMAIL" = "<old_email>" ]
then
    an="Eric Barendt"
    am="<new_email>"
fi
 
export GIT_AUTHOR_NAME="$an"
export GIT_AUTHOR_EMAIL="$am"
export GIT_COMMITTER_NAME="$cn"
export GIT_COMMITTER_EMAIL="$cm"
