[DMyachin]

Thanks for your PR!

Tested it locally and it works as expected.

I made a couple of comments/questions

@pnu-s ?

Sorry for the delayed answer!

My proposal was not just to use the exit-code name rather than no-exit-code but to offer the user to specify its error code (0 to avoid failing totally, 1 to overwrite the current behavior which returns the number of trackers, or other)

That would improve the user experience in my opinion

In terms of code, it would mean:

• if no trackers, always return 0
• if trackers, either return the specified exit code if existing otherwise the number of trackers as a RC

See new commit

    if all([counter, forced_code is not None]):
        sys.exit(forced_code)
    sys.exit(counter)

0 is False in Python.

If counter is not zero (has trackers) AND code overwriting is set to any int value, the value will be used else counter.

LGTM, thanks for your quick changes!

You'll just need to remove that extra blank line to make the linter pass, and I'll be able to merge it 🚀
