You can mount an ISO image of a CD to your filesystem in linux. That means you can read files from the image without burning it onto a disk first.
Make a directory to mount the image to, for example:
mkdir /mnt/isoMount the image:
mount image.iso /mnt/iso -o loop,roIf you get a 'you must specify the filesystem type' or 'Permission denied' error, you probably forgot or mistyped the
-o loop,ro part.
