groups: As a courtesy, I include it

I have the groups command on my list of applications to share, and I was sorely tempted to leave it out, except I couldn’t think of a good reason. So here goes.

Best I can tell — and please, as always, let me know if there’s some sort of kung-fu master way to use this — groups only returns the groups a user account belongs to.

Ergo,

And I think that’s it. The man page is like four lines long, and I swear, there’s nothing there except groups [user], end of page.

Now if you want to know what groups are available on a machine, I usually cat /etc/group, which in Arch spits out a list.

groups is part of shadow, which is the go-to package for everything login-ish for Arch. For Debian, I think that’s passwd. And that … is all I’ve got. 😉
