Bash TCP conection feature

Bash support tcp connection out of the box :)

So you can write something like

#!/bin/bash
webhost="gioorgi.com"
exec 5<>/dev/tcp/$webhost/80
echo -e "GET / HTTP/1.1\\r\\nHost: $webhost\\r\\nContent-Length: 0\\r\\n\\r" >&5
# get reply:   HTTP/1.1 301 Moved Permanently^M
cat <&5
