command line help - pretty basic
Hello! I would like to know if there is a command that will list groups. The reason I would like to do this is so that ordinary users will have access to hardware such as modem and storage devices. By default, my system (Vector Linux 4.3 - which makes my tired old 'puter gallop like a mustang) seems to only allow root access to these things.
Will it work if I create groups named "cdrom, modem, usb" and give members of those groups access to the devices, then add the privileged users to the groups?
Does that sound about right? Can anybody suggest another way to do it.
But first I'd like to peek under the hood of my system and see what groups are already there. Ideally, there's already a cdrom group with root as its only member, but I ain't bettin' the farm on it.
I know how to create groups, change permissions and all that. Stupid as it may sound, I do not know how to list the groups. I'd like to know how to do that.
Thanks in advance!
(I've already googled this to death, and I still haven't found a convenient way to list groups.)
