DLT Roll to last session automatically!

[jackps]

Dear all
Just want to ask if there is any command that will fast forward to the last end session of a dlt tape?
Every day i got to type this command "tctl -f /dev/rmt1.1 fsf 18" where 18 is the number of session i want to fast forward and it is different on differ day, i want to see if this can be automated!

It will be great if a simple example script!

Thx alot

Jack

i am not able to find a DLT or help from man page, so here is the theory. you can execute 'tctl fsf 1' to move ahead one mark. if there is no next file mark, does this return something larger than zero? if so then it will be a simple conditional test.

you can test this by executing the command until it reaches the end, say you have moved to mark 18 and there are no more marks, then you run the command again. after that, execute 'print $?' to see the return code from the command. if it is not zero then it can be easily coded.
