Following command will mount your iso file named: fileName.iso to /mnt
directory. If you look into /mnt, you will see the content of the .iso
file as if you would burn it to CD/DVD and mount it. If you want to
copy the content to an empty partition for further work or booting, you
will need to create, format and mount it as destinationDir.

following command will recursively copy the content of the iso file 
 into destinationDir and preserve the file timestamps. the rsync
command is an alternative to cp which works incrementally and/or if you
want to see progress.

Following command will unmount the .iso file from /mnt whne you are
done with using it.
