  1. 8. Getting Admin Power

    Last How to Get the Admin Super-Powers.

    To Login as SuperUser:

    sudo su

    Authenticate with the User Admin Pass.
    If Got “User is Not in Sudoers file” then see: How to Enable sudo
    Then to Logout:

    exit

    To Protect your System from the potential Damage of an Hazardous Crazy Command Execution the Logout should be executed every Time your Setup is Achieved!
    Finally, to Execute a Single Command as SuperUser:

    sudo su -c 'myCommand'

    Or:

    sudo myCommand

    So for instance to List the Protected root Directory try to run:

    sudo ls /root
