Is there a command to list all unix group names?

Question

I want to create an administrator web page that has the list of Linux accounts’ group names. Can anyone tell me if there is a simple way other than /etc/group which parses the entire readable file? 

Answer 1

Use this command below to list all local groups: 

cut -d: -f1 /etc/group | sort
