The root user in Linux is the user which has administrative access to your system. Normal users do not have this access for security reasons. Kubuntu does not enable the root user. Instead, administrative access is given to individual users, who may use the "sudo" application to perform administrative tasks. The first user account you created on your system during installation will, by default, have access to sudo <emphasis>s</emphasis>uper <emphasis>u</emphasis>ser <emphasis>do</emphasis>. You can restrict and enable sudo access to users with the <application>Users and Groups</application> application (review the <ulink type="help" url="help:/kubuntu/keeping-safe/">Keeping Safe</ulink> documentation for more information).

In days gone by, this was the way the user interacted with the computer; however, Linux users have found that the use of the shell can be quicker than a graphical method and still holds some merit today. Here you will learn how to use the terminal.

The <application>locate</application> command will search for any filename you specify. It uses an index of the files on your system to work quickly. To update this index, run the command <application>sudo updatedb</application>. This command is run automatically each day if you leave your computer on. It needs to be run with administrative privileges (see <xref linkend="root-and-sudo"/>).
