Problem with wrong names for committer or author on git for a number of commits? This can be fixed either by git rebase or by git filter-branch.

Note of caution: This script will change SHA1s for all previous commits.

Create a shell script with +x permissions

#!/bin/sh

git filter-branch -f --env-filter '

an="$GIT_AUTHOR_NAME"
am="$GIT_AUTHOR_EMAIL"
cn="$GIT_COMMITTER_NAME"
cm="$GIT_COMMITTER_EMAIL"

if [ "$GIT_COMMITTER_EMAIL" = "your@email.to.match" ]
then
cn="Your New Committer Name"
cm="Your New Committer Email"
fi
if [ "$GIT_AUTHOR_EMAIL" = "your@email.to.match" ]
then
an="Your New Author Name"
am="Your New Author Email"
fi

export GIT_AUTHOR_NAME=$an
export GIT_AUTHOR_EMAIL=$am
export GIT_COMMITTER_NAME=$cn
export GIT_COMMITTER_EMAIL=$cm
'

Once done, run the push command to update origin. Please note that this will override SHA1s irrevocably at origin

git push origin +main
