User/group exercise

The problem is to create a group called sysadm.

abraham needs to be a secondary member of this group.

leah is a secondary member of sysadm group.

rachael has no interactive login is not a memberĀ  of sysadm.

For simplicity make the password equal to blackhat


Next objective: Make a folder /redhat/sysadm group ownership should be sysadm. /members of sysadm should have read, write and execute permissions. Files in that folder should be inaccessible to all other users. Files in that folder should automatically be a member of group sysadm.

Simple. Nothing fancy.
