Mounting iso-image as filesystem
Good thing in Linux is its flexibility. There are many things “built-in” the operating system itself that you might not be aware of. Lets take the basic command mount, which most users should be familiar with. With this command you can do more than just mount your physical disks.
Lets say you have an iso-image on your filesystem, and you want to check its contents or get just couple of files out of it. You do not have to burn it on cd or dvd, since with mount-command, you can mount that iso-image as a loopback device. On command line, run
mount my-image.iso /media/cdrom -t iso9660 -o loop
assuming the file is my-image.iso and you want to use mount point /media/cdrom. You can use other mount point if you want.
