NODEJS process info

Question Description

How to get the process name with a PID (Process ID) in Node.JS program, platform include Mac, Windows, Linux.

Does it has some node modules to do it?

Practice As Follows

Yes, built-in/core modules process does this:

So, just say var process = require('process'); Then

To get PID (Process ID):

if ( {
  console.log('This process is your pid ' +;

To get Platform information:

console.log('This platform is ' + process.platform);

Note: You can only get to know the PID of child process or parent process.

Updated as per your requirements. (Tested On WINDOWS)

var exec = require('child_process').exec;
var yourPID = '1444';

exec('tasklist', function(err, stdout, stderr) { 
    var lines = stdout.toString().split('\n');
    var results = new Array();
    lines.forEach(function(line) {
        var parts = line.split('=');
        if(items.toString().indexOf(yourPID) > -1){
        console.log(items.toString().substring(0, items.toString().indexOf(yourPID)));

On Linux you can try something like:

var spawn = require('child_process').spawn,
    cmdd = spawn('your_command'); //something like: 'man ps'

cmdd.stdout.on('data', function (data) {
  console.log('' + data);
cmdd.stderr.on('data', function (data) {
  if (/^execvp\(\)/.test(data)) {
    console.log('Failed to start child process.');
