Uncompress Using a Pipe 1

[ScottAB]

I received an Oracle export today that was suffixed with a .Z. No problem; it's compressed using the compress command. However, when I go to uncompress it, I receive an error saying "corrupt input", and the process fails. I called the person I received the export from and he indicated that the file was compressed using a "pipe". He went on to explain that all I needed to do was to:

Create a pipe;
uncompress filename pipename &;
import pipename

Sounded simple enough; however, I can't get it to work. My contact is now gone for the day. Can anyone elaborate on this a little more?

hi,

you have to create a file which is a pipe file to do
this use the mkfio command

i.e. mkfifo tempfile

when you do an ls -l of tempfile it will have a p at the front of indocating a pipe then use this pipe file to uncompress i.e.

uncompress filename.Z > tempfile & ( in background)
