All of the files on a Linux system have permissions that allow or prevent others from viewing, modifying or executing them. The superuser "root" has the ability to access any file on the system. Each file has access restrictions, user restrictions, and an owner/group association.

To view and edit the permissions on files and directories, open the <menuchoice><guimenu>System Menu</guimenu><guimenuitem>Home Folder</guimenuitem></menuchoice>, right-click on a file or directory, then select <guimenu>Properties</guimenu>. The permissions are found under the <guilabel>Permissions</guilabel> tab and allow for the editing of all permission levels, if you are the owner of the file. Advanced permission settings (such as in the <guilabel>Advanced Permissions</guilabel> tab) are outside of the scope of this guide.

The root user in GNU/Linux is the user which has administrative access to your system. Normal users do not have this access for security reasons. However, Kubuntu does not include 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. You can restrict and enable sudo access to users with the <application>Users and Groups</application> application (see <xref linkend="users-and-groups"/> for more information).

Sudo will remember your password for a set amount of time (15 minutes by default). This feature was designed to allow users to perform multiple administrative tasks without being asked for a password each time.
