Greetings,

I'm looking for a way to manipulate a CD-ROM drive from within a shell
script (ksh, perl, python, whatever).  I need to be able to eject the
tray, and also query whether the tray contains a disc or is empty from
within the program.  The first is easily accomplished with a utility like
"eject", but how about the latter?  Is there an easy way to tell whether
a FreeBSD system's CD-ROM drive contains a disk or not?

Regards,
Graham
