Answer

1. Verify if the group admin exist, if it doesn’t exist, create the group

In my lab, it doesn’t exist, so, to create the admin group, use the command,

[root@tekneed ~]# groupadd admin

[root@tekneed ~]# cat /etc/group |grep admin
printadmin:x:995:
admin:x:1001:

2. Create the users, ben & martin, and add them to the admin group

[root@tekneed ~]# useradd -G admin ben

[root@tekneed ~]# useradd -G admin martin

3. Verify that the users have been created and added to the admin group

[root@tekneed ~]# id ben
uid=1001(ben) gid=1002(ben) groups=1002(ben),1001(admin)

[root@tekneed ~]# id martin
uid=1002(martin) gid=1003(martin) groups=1003(martin),1001(admin)
