Oh, yes it is.  You have to be the root user to use it.  Either log in
as root or, as a normal user, use the command "su -" and give it
the root password.  You then become the root user.

Do the commands you need.  When it's time to stop being the root user,
type in "exit" and you become the normal user again.  DON'T REMAIN AS
THE ROOT USER ANY LONGER THAN YOU HAVE TO!  You can do a lot of damage
to your machine if you're root and you're not careful!
