Well, the Bash of modern versions(>=2.0) provides a featured concept, called Process Substitution.
However, it works like chaos and functions limitedly.
Anyone can give some advanced way to make co-process?

I use ksh coprocesses all the time. Many of the scripts that I have posted here use coprocesses.

A simple script would be this automated ftp script.

This thread has a script that uses mutiple coprocesses.

And then, there is this.
