How can I search for a string that someone changed with git?

Question

I would like to search for a specific string using git grep but I would like to filter the results by using git blame to know that the string I'm looking for was changed by a specific person.

I just don't know how can I combine them to get the results I want.

Thank you for your help.

You can write a little shell script to accomplish this:

git rev-list --author=Doe HEAD |
while read rev; do
    if git show -p $rev | grep "PATTERN" >/dev/null; then
        echo $rev
    fi
done

This will output the SHA's that are reachable by HEAD that have an author of "Doe" and have "PATTERN" in the commit content's.
