How not to check files with RuboCop

While using rubocop on the project it came out that a lot of fixes had to be done, not only those connected with my task.

So I came up with the idea to list and fix only these files that I have changed.

Two of them were:

- bin/start-dev
- config/config.yaml

Calling the command directly on those files:

rubocop bin/start-dev
rubocop config/config.yaml

forced rubocop to check them and throw offenses that were not supposed to appear despite the fact, these files were not included as files to be checked in:

rubocop/config/default.yml

So by default rubocop ignores such files.
