How to mount .ISO files and interact with the contents over a virtual directory:

This is easy in Linux. First you must make a directory for the mount to exist in (you may create the directory as a non-root user).

$ mkdir /home/username/iso

Then, simply mount the ISO making reference to the directory you just made …

$ mount NameOfTheISO.iso /home/username/iso -o loop

The loop device is a device driver that allows an image file to be mounted as though it were a normal block device, such as a CDROM.

“When you’re done, simply unmount the ISO …

$ umount /home/username/iso

RSYNC Sample command:

rsync -ra --progress --size-only /home/joe/mounts/99_L /media/disk/source
