Disappearing coprocess output

[d9720267]

Hi,

I am trying to run a program called netcat (

http://www.atstake.com/research/tools/network_utilities/)

as a coprocess. As far as I know, the following command should start it a as a coprocess:

netcat -l -p 80 |&

(The -l -p 80 tells it to listen to port 80)

Then if I want to get a line of its output, the following should do it:

read -p line
print $line

However, thae read command just hangs, even when I know netcat is outputting something. Where is it outputting to, and how can I get at it?

Thanks for your help!

Doug

you may stop the coprocess and see any output of the process. If it has a output file, then try:

exec 3< output_file
read -u3 line
print $line
