the tar file is actually is a netcat utility and this netcat fit for unixware OS

but as we see the results from the following "curl" is "not in compressed format

Someone have an idea why?

If it's not in compressed format, you won't need to uncompress it, correct? So why not try just untarring it? – marcusw Jan 31 '11 at 19:13
Is there a reason you're piping to uncompress before tar? – Matthieu Cartier Jan 31 '11 at 19:14
OK but after I remove the uncompress I get : tar: This does not look like a tar archive tar: Skipping to next header tar: Error exit delayed from previous errors – yael Jan 31 '11 at 19:16
@marcusw: According to GNU file, the file served at that URL is compressed ("SCO compress -H (LZH) data") – grawity Jan 31 '11 at 19:18
@neurolysis: Because the input is `compress`ed, and must be uncompressed before giving it to tar. (Some implementations of tar can recognize compressed tarballs, but not all of them.) – grawity Jan 31 '11 at 19:20
