I have a group that all users on the system share. The group name is common and it is to allow for a universal fileshare for everyone on the machine. How would I make it so that all new users are added to this group by default? [No manual intervention needed on an adduser command]

What operating system? Remember unix.SE is about any Unix or Unix-like operating system like Solaris, HPUX, Debian/Linux, MacOS/X... Several of those have a adduser command, not all of them do.– Stéphane ChazelasCommented May 10, 2013 at 17:08

Set ADD_EXTRA_GROUPS and EXTRA_GROUPS in /etc/adduser.conf. From the manpage:
ADD_EXTRA_GROUPS
Setting this to something other than 0 (the default) will cause
adduser to add newly created non-system users to the list of
groups defined by EXTRA_GROUPS (below).
EXTRA_GROUPS
This is the list of groups that new non-system users will be
added to. By default, this list is 'dialout cdrom floppy audio
video plugdev users games'

Which man page are you referencing? I'm not finding this for the
useraddoraddusercommands. I'm on Fedora if that matters.– slm ♦Commented May 10, 2013 at 16:36 -

1Yeah I tried that too, don't have that on Fedora either. Is this file a Debian/Ubuntu only thing?– slm ♦Commented May 10, 2013 at 16:42

Turns out the file is called /etc/default/useradd on RHEL distros. It only contains a variable,
GROUP=...where you can specify the default group you want to have added to new user accts. Untested, but you may be able to give it a list like so:GROUP=500,600,400– slm ♦Commented May 10, 2013 at 16:55 -
