如何杀死正在并行运行的子进程

Question

I have spawned many child

var spawn = require('child_process').spawn,
  newProcess1 = spawn('node', ['File1.js']),
  newProcess2 = spawn('node', ['File2.js']),
  newProcess3 = spawn('node', ['File3.js']);

which will run parallely.If newProcess1 fails then newProcess2 and newProcess3 must be stopped or killed if it has not started.

How can kill a child process?

Answer 1

newProcess1.on('close', function (code) { 
  console.log('child process ' + newProcess1.pid + ' exited with code ' + code); 
  newProcess2.kill();
  newProcess3.kill();
});
