Hello Suraj,
I suspect that you have been using child_process.exec(). Look into
child_process.spawn()<http://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options>
.
It returns an EventEmitter and allows you to add stdout, stderr and exit
listeners that will be called asynchronously. Here is an excerpt from the
node.js doc on how to use spawn():
var spawn = require('child_process').spawn,
ls = spawn('ls', ['-lh', '/usr']);
ls.stdout.on('data', function (data) {
console.log('stdout: ' + data);});
ls.stderr.on('data', function (data) {
console.log('stderr: ' + data);});
ls.on('exit', function (code) {
console.log('child process exited with code ' + code);});
