Hi

I trying to copy a bunch of files from 3590 media to disk using the following dd command "dd if=/dev/rmt/0 of=xxx.txt ibs=8000 cbs=80 conv=unblock". The output is only the 1st file. There 20 files on the 3590. How do i modify the dd command to retrieve all the files?

Code:

dd if=/dev/rmt/0 of=*.txt ibs=8000 cbs=80 conv=unblock

try this........the "*"(star) is a wildcard indentifier.......

May be each file is in a "session" of dd.
Try to use the non-rewind tape device, and, after you get the first, repeat the command to retrieve the next. Its important to specify the non-rewind device here, otherwise, the tape is rewinded after the dd command finish. You may use the mt forward space options to positioning the tape in an arbitrary position. Of course, again, you must use the non-rewind device to to this.

Hi

Tanx y'all for helping. I was away to a place the net doesn't exist.

Yea, the problem was due to the fact that the no rerwind option was left out of the command. So it read and writes the first file only and stops.

Much obliged guys.
