cmd.js

var express = require('express'), exec = require('child_process').exec;

var app = express.createServer();
app.use(app.router);
app.get('/ls', function(req, res) {
	exec('ls . ', function(error, stdout, stderr) {
		console.log(stdout);
		res.write(stdout, 'utf-8');
		res.write(stderr, 'utf-8');
		if(error) {
			throw error;
		}
		res.end('');
	});
});
app.listen(8080);
console.log('server ' + process.pid + ' running on 8080 port...');
