=====Sudoers Options====
REdhat recommends rather than modifying the sudioers file itself you and entries to the **/etc/sudoers.d/** directory
Permissions are similar for example
[student@servera ~]$ sudo cat /etc/sudoers.d/operator1
operator1 ALL=(ALL) ALL
Here is how you would create file to grant sudo permissions for the Admin group
echo "%admin ALL=(ALL) ALL" >> /etc/sudoers.d/admin
