I'm sure there are better ways, but none I can think of at present. This
works on a mounted or unmounted cd in /dev/cdrom
$ strings /dev/cdrom | head -2
CD001
LINUX Red Hat Linux/i386 8.0
Since you would know the volume name you are looking for, you should be
able to pass the output to grep. Something like this should work:
#! /bin/bash
strings /dev/cdrom | head -2 | grep -q "Red Hat Linux/i386" || {
echo "Error, Volume ID doesn't match!"
echo "Exiting"
exit 1
}
