====== Deleting a User and Removing a User From a Group ======
\\ 
\\ 
If you want to remove a user from a group you can use the following command:\\ 
\\ 
        sudo deluser <username> <groupname>
\\ 
So to remove user 'newuser' from the group 'adm' you would type:\\ 
\\ 
        sudo deluser newuser adm
\\ 
A similar command can be used to delete an entire user along with it's home directory:\\ 
\\ 
        sudo deluser <username>
