Hi,

any differencies if you don't use the '-'?
tar tvf scripts.tar ?
If this tar is from SGI, for example, use:
'dd if=scripts.tar bs=1024k|tar xvf -'

Else transfer it to windows and try to read it with zip, if the error is the same, then I believe the file is corrupt.

Hi Nyaga,
Thanks for the reply.here is the output.I was able to extract only one file the last one.
Also using tar tvf scripts.tar doesn't makes any difference

daimler:/var > dd if=scripts.tar bs=1024k |tar xvf -
home/unixadm/vkarmak/
home/unixadm/vkarmak/UnixNP
tar: Skipping to next header
13+1 records in
13+1 records out

Hi again,

the first part is a directory only, so one file is ok.
Maybe the error is from the creation of the tar file and there's nothing more inside?
How big is the tar file?
Have you tried winzip?

Hi,

Tar file is 14MB in size. I tried winzip but no files are visible inside there.

Looks to be corrupted

Hi again,

from:
13+1 records in
13+1 records out (with bs=1024k)
14 MB looks ok

home/unixadm/vkarmak/UnixNP
has only 1903 bytes?

I believe also another blocksize wouldn't change anything, but you could try bs=128k
