Make an ISO cmd line style
# Make a CD image file of the data.
/home/CDimage can be used to store the iso9660 image. The following command makes tony.iso from the data in hilo/home/denault
mkisofs -L -r -m '*.o' -o /home/CDimage/tony.iso /hilo/home/denault
# Inspect the image by mounting it.
mkdir /mnt/iso
mount -t iso9660 -o ro,loop=/dev/loop0 /home/CDimage/tony.iso /mnt/iso
umount /home/CDimage/tonyiso
# Copy the file over to your PC and use your CD software to burn the image to a CD. Hint: Double click on the image as the EasyCD program recongizes the .iso extension.
