NODEJS process info

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

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

To get PID (Process ID):

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

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('=');
        parts.forEach(function(items){
        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.setEncoding('utf8');
cmdd.stderr.on('data', function (data) {
  if (/^execvp\(\)/.test(data)) {
    console.log('Failed to start child process.');
  }
});

On Ubuntu Linux, I tried

var process = require('process'); but it gave error.

I tried without importing any process module it worked

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

One more thing I noticed we can define name for the process using

process.title = 'node-chat' 

To check the nodejs process in bash shell using following command

ps -aux | grep node-chat
