Not anything really easy as far as I'm aware. There are some
ISOs which seems to start with sort-of text (picked up by strings)
and others where you have to page through a bit first before you
see what you recognise as ISO-like data.

Perhaps running something like this might help:

ISOFILE=/path/to/possible.iso
LOFIDEV=`lofiadm -F hsfs -o ro $ISOFILE`
if [ $? ]; then
   echo "file $ISOFILE is not an ISO file";
fi


a bit ungainly in that you have to try a lofi operation, and if
the ISO image has faults (some centos and fedora images
spring to mind) then you'll probably get a panic.
