Erklärung:

• NUMSLOTS=10 - this is the number of slots in my tape library.
• FIRSTSLOT=1 - the first slot to deal with
• CHANGER=/dev/pass4 - the device for the tape changer
• TAPEDRIVE=/dev/sa1 - the device for the tape drive
• MTXCHANGER=/usr/local/sbin/mtx-changer - the path to my mtx-changer script
• MT=/usr/bin/mt - the path to the mt(1) binary

• SLOTS=jot ${NUMSLOTS} ${FIRSTSLOT} ${NUMSLOTS} - this generates a sequence of 1..10 (for my ten slots)
