Stop node.js program from command line
command, node.js
Solution
To end the program, you should be using Ctrl + C. If you do that, it sends `SIGINT`, which allows the program to end gracefully, unbinding from any ports it is listening on.

Problem
I have a simple TCP server that listens on a port. ``` var net = require("net"); var server = net.createServer(function(socket) { socket.end("Hello!\n"); }); server.listen(7777); ``` I start it with `node server.js` and then close it with Ctrl+Z on Mac. When I try to run it again with `node server.js` I get this error message: ``` node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: listen EADDRINUSE at errnoException (net.js:670:11) at Array.0 (net.js:771:26) at EventEmitter._tickCallback (node.js:192:41) ``` Am I closing the program the wrong way? How can I prevent this from happening?
