From: http://www.dzone.com/snippets/execute-unix-command-nodejs

To execute shell commands:

var sys = require('sys')
var exec = require('child_process').exec;

exec('command', function (error, stdout, stderr) {});

From: Run shell script with node.js (childProcess),

To run a program bar.sh in your home folder with the argument 'foo':

var foo = 'foo';

exec('~/bar.sh ' + foo,
  function (error, stdout, stderr) {
    if (error !== null) {
      console.log(error);
    } else {
    console.log('stdout: ' + stdout);
    console.log('stderr: ' + stderr);
    }
});
