View content of ISO file in Linux without burning it to disc

To view and use a CD or DVD’s ISO without needing to burn it to disc is to mount it as a loop via the loop option.

Assuming mycdrom.iso is the ISO file, the following example will mount it to /mnt/cd

$ mkdir /mnt/cd
$ sudo mount -o loop -t iso9660 mycdrom.iso /mnt/cd

You can now navigate to /mnt/cd to view the content the ISO file.

loop device need to be enabled when compiling the kernel for this to work. Most major Linux distributions already have this enabled in their default kernel.
