Just a FYI: it's HIGHLY recommended that you NOT log into the root account. Rather, if you need root privaleges, use the command
With full root privaleges at all times, there is little stopping you from deleting/modifying crucial system files, as well as accidentally doing other problematic things. If you only give yourself permissions when you need them, you will avoid most of this, as you generally have a specific action in mind when you need these privs anyway.
