Thanks. To update only your commits and not all ( even if not yours):

#!/bin/sh

git filter-branch -f --env-filter '
OLD_EMAIL="xxxxxxxxxxxxxxxxxxxxxxxxxx"
CORRECT_NAME="zzzzzzzzzzzzzzzzz"
CORRECT_EMAIL="yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
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
'  HEAD

Thank you so much!

git filter-repo solution:

git filter-repo --preserve-commit-hashes --name-callback "$(cat <<'EOF'
return b'<replace everything between the quotes with your name>'
EOF
)" --email-callback "$(cat <<'EOF'
return b'<replace everything between the quotes with your email>'
EOF
)"

If you had signed your commits before this, note that the above command will remove those signatures. For me, this answer was useful to resign all commits without loosing commit dates.

Works good, except merge commits, where it still shows the another user

Work fine. Thank you.

Good, really be helpful!

We love this script, thank you 💯
