I use following command to restore data from my cpio tape archive:
$cpio -icvd < /dev/rct0
But this'll restore all tape contents to the current path, what if I want only selected files from the tape, suppose I want
/home/compdir/home2/Rev83/data/PL/01/*.*
files to be restored from tape archive to my current path only, nothing else, which command I should use to achieve this? Any help would be highly appreciated.
You can simply specify extraction patterns to cpio, but I prefer to use pax when redirecting a restoration....
You'll have to adjust this to your specific circumstances, but say I have a cpio archive, /var/tmp/tmp.cpio (this could just be your tape device), and I want to restore /home/zb/tmp/*something* to /var/tmp/output... then I'd do...
# pax -r -s ',^/home/compdir/home2/Rev83/data/PL/01,/home/temp,' -f /dev/rct0 "*PL*"
UX:pax: WARNING: /dev/rct0 : This doesn't look like a tar archive
UX:pax: WARNING: /dev/rct0 : Skipping to next file...
UX:pax: ERROR: *PL* not found in archive
With the cpio command, you probably need to include the leading "/" in the pattern name, otherwise it will not match any files in the archive.
Unfortunately I'm at home at the moment so do not have access to a tape drive to test pax reading from cpio archives stored on tape - on my Linux box at home it can read a cpio archive file ok. Which OS are you using?
EDIT: with the pax command, try something like this
my dear thnx for your prompt reply, but still no joy.
Code:
# pax -r -s ',^/home/compdir/home2/Rev83/data/PL/01,/home/temp,' "*PL*" < /dev/rct0
