Node.js NODEJS 进程信息

是的，内置/核心模块process可实现以下功能:

那就说var process = require('process');吧

要获取PID(进程ID):

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

要获取平台信息:

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

Note:您只能了解子进程或父进程的PID.

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)));
         }
        }) 
    });
});

在Linux岁时，你可以try 以下方式:

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.');
  }
});
