Rename commit author in git

In some extremely rare cases you end up pushing data to the repo with the wrong credentials. If you are the only author and you’re as picky as I am, it can be corrected easily:

git filter-branch -f --env-filter
"GIT_AUTHOR_NAME='Stan Smith';
GIT_AUTHOR_EMAIL='stansmith@cia.gov';
GIT_COMMITTER_NAME='Stan Smith';
GIT_COMMITTER_EMAIL='stansmith@cia.gov';" HEAD
git push --force

In the case of there being multiple people working on a project, you may want to use the following gist posted by anonymous: https://gist.github.com/anonymous/2523336/ (again, followed by git push --force).
