建组，然后直接杀进程组吧。

```
const spawn = require('child_process').spawn;
const script = `${__dirname}/timeout_task.sh`;
const p = spawn(script, { detached: false, shell: true });

p.stdout.on('data', (data) => {
// do something
});

p.stderr.on('data', (data) => {
// do something
});

p.on('exit', (err) => {
// do something
});

setTimeout(() => {
console.log(process.kill(-p.pid, 'SIGKILL'));
}, 1000);

```

A 进程里开 fork B 进程，B 进程里再开 N 进程，关闭，直接关 B 进程即可
