Quickly re-launch your script (python for example)

Very useful for test a script. After launch this command, you only have to press ENTER for launch your script again. I work with screen and tape ENTER instead of '!!'+ENTER

If you break your script with CTRL-C, it will wait for press ENTER and will re-launch

You can write like it : while read -p "Press ENTER" ; do python ; done

Create a Bash command server - You can send it scripts or commands to execute

Allow to launch nc like a daemon, in background until you still stop it.

(like this command: http://www.commandlinefu.com/commands/view/9978 )

For send script or commands from the client to the server, use nc too, like that :

cat script.sh | nc server 1025

echo "service openvpn restart" | nc server 1025

The loop's inside doesn't do anything, but we can add echo -e "\nCommand received\n" .

while ( nc -l 80 < /file.htm > : ) ; do : ; done &

Daemonize nc - Transmit a file like a http server

Allow to launch nc like a daemon, in background until you still stop it.

You can stop it with kill %1 (jobs method) or kill PID.

The -k option can force nc to listen another connection, but if you use redirection, it will work only one time.

The loop's inside doesn't do anything, but we can imagine to send a message to screen when a connection is established
