The question was something along the lines of "How do I sum up who most often touch which files".
The purpose seems to be some analysis regarding who intelectually owns pieces of code within a repository.
I'm a component lover, so for me it seems like there is a monolith to be broken down :)
You can try and run this command in any repository, and it will give a list of commits, with short-sha, author-name and then sum what files were affected by this commit.
This information could be used in a script to populate the intellectual overview database.
git log --name-status --pretty="%h(%an) - %n"
git log gives us a list of the commits on the current branch we are on.
We could add a --all to see history from all branches, but don't get me started on long lived branches.
--name-status prints out for each commit what files where affected and how.
--pretty="%h(%an) - %s" gives us the shortsha(%h) the authorname (%an) and the commit message subject (%s). This should be enough information for us to script our way out of our trouble, just as we like it.
Enjoy :)
