going to brown whole damn grace but I have to explain the joke. Sudo ( s uper or be do ) is an application Unix Operating System used to perform actions with root privileges from user accounts. That should be worth. If you still do not understand, forget it. Anyway, practical example

dani @ master: ~ $ sudo apt-get install ssh
