Git command for count of commit messages containing a string, per user

Question

I know about git shortlog -sne, and git grep, but I need to kinda combine the two.

I'm searching for the number of occurrences of a string in the commit message, per user. I'd like the output to be:

Will: 54
Dave: 34
... etc.

Can someone help?

If by git sne you mean git shortlog -sne then it can take a --grep option to grep the commit messages.

git shortlog -sne --grep="a string"
