From #846 (comment)_

But if you have jobs with the same name – all of them will be run. Do you find this useful?

Yeah, I think that would be fine. And also as mentioned in #846, it would be great if one could also run (only) groups by their name.

I'm also wondering if all those three (commands, jobs, and groups) could be merged into one option, let's say --only THING would run only all commands, jobs, and groups named THING. Not sure for example if commands and jobs can coexist, or if there's much use for three separate options for these as they're kind of mutually exclusive anyway (unless e.g. --commands FOO --jobs BAR would run commands FOO and jobs BAR. Anyway mostly jut thinking aloud, not refined ideas in any way.
