commandline help needed
 

hello, i have recently learned how to add and delete users and groups to my linux system via the commandline. is there a command to see which groups and users have an account on the system? (i can check via the gui tool in gnome however, but i would like to be able to check this information via the commandline). thanks.

cat /etc/group and cat /etc/passwd does it for me.

thanks chris :)
