How to list existing users?

stefaandk · 06-26-2005, 07:18 PM

Hi,

Looking for a command that shows me which users currently exist.

Cheers,

Tinkster · 06-26-2005, 07:19 PM

cat /etc/passwd

off course, thx!

Following up from this is there also a way to list groups rather then users?

Matir · 06-27-2005, 10:17 PM

cat /etc/group

cat /etc/group |grep [5-9][0-9][0-9]

if you don't want to list all the group

I'm just a newbie as well, but couldn't you just use "who" to see who is logged on to the system? Also, I'm not sure but can't you also use "groups" for the groups?

"groups" will only show group info about yourself or a specific user. "who" will only list people logged into the system, but not every user that has an account on the system.

In fact it doesn't list a single one on my machine(s) ;}

and... If you want just the username listed and not the whole line you can just use :

awk -F: '{ print $1 }' /etc/passwd

For groups... just replace /etc/passwd by /etc/group

That's not "wrong" - but it's limited to your distros
view of the linux world. To create a group per user
is not necessary, it's something that DeadRat based
distros for instance will do.
