I am unsure this solves the question. Is the OP looking for anyone who modifies any set or subset of files in any clone or in the upstream repo? This is generally considered a "watch" function and is sometimes available on the upstream repo manager, like GitHub/GitLab/BitBucket rather than in core git, so take into account changes made anywhere. If that is the case and the watch functions are not sufficient, you might have to put the hooks on your upstream rather than in your clone. Just my thoughts, Randall
