Set up the icon by right-clicking the Desktop and selecting "Link to Application." Right-click the icon and open Properties. Name the icon start-dar-archive, click the Application tab and enter these values:

• Name: start-dar-archive
• Command: sudo sh /cdrom/dar_backup-k.sh

Copy the file to /home/username/knoppix-mod.
