Parse the output of 'echo "sta sd=<device-name>"|bconsole -c ...' or
use btape.

Or Perl, (ba)sh, or any other script language... but yes, I agree.
I'd actually try to create an easily configurable script and publish

I've got a script I use to unload volumes that are full and eligible
for safe storge and semi-automatically load and scan newly added
volumes which might be a good starting-point for you. It's Perl, it's
ugly, but you can have it if you like... just drop me a note.
