Hmmmmmm, /me looks at man adduser....
Ah, now I see. adduser is a new! improved! useradd that really is
better. I first saw it on Red Hat <small number> back in the day and
it looked like a half-baked waste of time. So I never used it again.
And on gentoo (my main distro) adduser is a symlink to useradd :-(
Adding users to groups normally confuses the daylights out of most
folk, they can't figure out how to do it and the man pages conspire
to make it more difficult than it should be. 'usermod -G <groups>
<user>' looks like it might do the thing, but it first removes all
existing groups, then adds just the ones in the <groups> list.
Confusing. It's meant to be used once when the user account is
created, but the man page doesn't say that. In desperation, 'sudo
vi /etc/group' becomes the tool of choice until one stumbles across
gpasswd in the dark (like I did)
adduser <user> <group>
gpasswd -a <user> <group>
are effectively the same. A good addition to adduser, especially as it
is the man page most folk would look at first
