How to find Secondary Group only?

Hi,

I would like to know how to find our secondary group of user only.

I have used the command id -Gn user1

it is showing both groups of user.

Primary and secondary group.

Code:
  id -Gn user1 | cut -d' ' -f2-

Or to store it:
Code:
[root@ns2 ~]# id -Gn scott
scott users staff
[root@ns2 ~]# G=$(id -Gn scott)
[root@ns2 ~]# G=${G#* }
[root@ns2 ~]# echo $G
users staff
