Root

root is a user that is currently installed by default. It is the most powerful user on a linux based computer system. It allows you to execute any command that is available to it.

It will even allow you to execute commands that are harmful to your system. For example, you could delete all of the contents of a folder, or important system files by accident.

It is very important that you be careful when using the root user.

You become root in the terminal activity, or in a Virtual Terminal like this:

su -

Note that the Root user is going to be disabled for security purposes. If 'su -' does not work for you, see: sudo.
