This is a snippet of the swcript we use to automate this. $AVAIL == a perl 
replacement for the available_media script...

$AVAIL | tail +5 | grep -v pool | grep -v CLN | grep -v present > $TMP1
#
## Sort out just full or frozen tapes
awk '{ print $4, $5, $1, $3, $9 }' $1 $TMP1 | egrep 'FULL|FROZEN' | grep TLD > 
$TMP2

There are probably 43 easier or more efficient ways to do this, but it works 
for us.
