We are doing backup remotely with cpio command. Our tape drive is with machine
'peach'. We do backup of machine 'backup_machine'. We have scripts to do it.
We have many systems but backup is done from one central machine. 

I don't understand shell script yet (working on it). It is very complecated. 
When I was running the bacup I got the process listing which shows :

  backup 22545 22544  0 11:53:41 ?         0:00 rsh peach -l tape dd conv=block obs=5120 of=/dev/nrst1 
  backup 22551 22545 35 11:53:41 ?         2:39 rsh peach -l tape dd conv=block obs=5120 of=/dev/nrst1 
  backup 22547 22545 18 11:53:41 ?         1:57 cpio -o 
  backup 22548 22546  0 11:53:41 ?         0:07 find /etc/aliases /etc/cshrc /etc/group /etc/hosts /etc/init.d /etc/motd /e

and some other which is our scripts.


Now, within a day or two I need to write a program which will make a listing of the
backup tapes. I looked at the cpio manuals but did not know what to do.

If any one can help me on this I will appreciate it very much. I use tar all the time 
but this is different. I loged in to 'peach' and tried 'cpio -tBi /dev/nrst1', it
didnot work.

Thanks for any info.
