Hi

I am piping some streams from a linux box using nc.

I am able to use this stream to compress using gzip, xz etc but I am unable to do it with 7z. I tried both the Cygwin version and the windows version.

Here is the client side

nc client_ip 9999 |pv|7z a -txz -so -si |cat > backup_12_12_2013.tar.7z

This does not work and throws

Error:
Incorrect command line

thanks
