Hi

what is the main difference between -G -g .which one is effective to enable permission for the user in a group

#usermod -G root littlemaster
usermod -g root littlemaster

as per the manpage, -g is the primary group, -G is additional groups

don't add users to the root group, that's really not smart. Why do you want to do this as opposed to use conventional existing privilege elevation mechanisms like sudo?
