It SAYS that there is a way to list the files. I've never succeeded in
getting it to work but it's a place to start.

That's because it doesn't write in either "cpio" or "tar"
formats, it has it's own.

If I remember correctly, both "tar" and "cpio" write the
file name/info as they write the file to tape (or tar/cpio archive
file).

"ufsdump" writes the list of files it's going to put in the archive
at the beginning, saving time if the file you want isn't on this
tape/file.

ufsrestore tvf

You can leave out the "v" in "tvf", it justs displays more verbose
info like when the archive was created which is one of the things
you are looking for.

Works great, been using this for years and never had any problems
with it listing the files from a tape or ufsdump file..

Since you wrote the tape with ufsdump, then the appropriate tool to
extract the contents is ufsrestore. Since all you want to do is
determine what each of the tapes contains then simply change to /tmp
and then do a ufsrestore -ivf /dev/rmt/1n will get an interactive
restore. Once it reads the table of contents you use cd and ls to
change directories and list the contents of the directories. Further
the ufsrestore -ivf /dev/rmt/1n will give a date and time that the
ufsdump occurred on

ufsrestore tf /dev/rmt/1n

The t means "show me the table of contents." The f means "use this
device/file", in your case /dev/rmt/1. I'm not sure how to get the
date of the archive, but when you restore the files, ufsrestore will
preserve the original modification time by default (if possible).
