hi,
How can i see what's on a tape?

Thanx
 
Not an easy question without a bit more info. However, for starters you could try either;

tar -tvf [tapedrive name]

or:

cpio -itvB < [tapedrive name]

It's good practice to annotate a tape with the command used to write it, for use in situations such as these!

Good luck.
 
if you have no idea what utility was used to write the tape, or just want the &quot;raw&quot; data, you could also use dd in this format

# dd if=/dev/rmt0 of=/tmp/tape.out bs=512 count=2

this would get 1k of info off of the tape. keep in mind the tape device might be a little different than the example.
 
I just want to see what files are on the tape and the size.

these are the devices:

rmt0 Available 04-B0-00-6,0 4.0 GB 4mm Tape Drive
rmt1 Available 04-B0-00-2,0 Other SCSI Tape Drive

the backup is done with the tar command


 
just like Ken had mentioned then

# tar tvf /dev/rmt0

or

# tar tvf /dev/rmt1

depending on which drive you put the tape in.
 
how long does it take to extract from tape??

ie tar -xvf /dev/rmt0

No response from tape!!
 
You should see activity on the tape drive right after you hit return. Does it error off?

Great!
Thanx for the response so far.

Can i just see the total size and number of files?

 
You can see the number of files on the tape using:

tar -tvf /dev/rmt0 | wc -l

The | is a 'pipe' and is located as the shift of the \ key on my keyboard. wc -l gives a count of the lines produced by the tar command. Perhaps someone can help with the total size part?

HTH
 
no error off crowe.

i can list tha tape contents (tar -tvf /dev/rmt0) tho.

cheers

Hmmm. Think I'm losing this a bit! If you can see the contents of the tape using the tar command then your tape appears to be working OK.
