codeowners-coverage also has a CLI. It works by loading a local Git repository, parsing its CODEOWNERS file, and crawling the disk for matches. To run, simply provide a path to a Git repository.

codeowners-coverage ~/go/src/github.com/docker/compose

In the event of a successful navigation, this will print JSON to stdout describing the coverage attributes of the repository.
