如何在nodejs中列出子进程

const { exec } = require('child_process');

exec('ls', (error, stdout, stderr) => {
  if (error) {
    console.error(`执行命令出错: ${error}`);
    return;
  }
  console.log(`子进程输出: ${stdout}`);
});

const { spawn } = require('child_process');

const ls = spawn('ls');

ls.stdout.on('data', (data) => {
  console.log(`子进程输出: ${data}`);
});

ls.stderr.on('data', (data) => {
  console.error(`子进程错误: ${data}`);
});

ls.on('close', (code) => {
  console.log(`子进程退出码: ${code}`);
});
