如何殺死正在並行運行的子進程

Question

我生了很多孩子

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

如果newProcess1失敗，則newProcess2和newProcess3如果尚未啟動，則必須停止或終止。

如何殺死一個子進程？

Answer 1

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