Redirect process stdin and stdout to netcat

Question

I have an embedded linux application with a simple interactive command line interface.

I\'d like to access the command line from telnet (or network, in general).

Answer 1

I found that by using bash v. >= 4.0 I can use coproc:

#!/bin/bash

coproc myapp
nc -kl -p 4000 <&"${COPROC[0]}" >&"${COPROC[1]}"

EDIT

I eventually incorporated a telnet server in my cli library. You can find the result on GitHub: https://github.com/daniele77/cli
