I think I understand what you are looking for.
The way I read the script and from what the previous unix guy told me, there should be 3 sections on the tape:
1) The password file, and the oracle user profile
2) The full backup of the entire unix system file structure
3) A full backup of the entire unix test box (done via remote shell in the backup script)
Knowing that, it seems like according to what you told me to do (List the contents on each), that it doesn't appear to be working right.
Here is a screenshot of the results. A picture is worth a thousand words here.
