在 vscode 的集成终端中运行命令后如何获取退出代码

Question

运行terminal.sendtext("some command")后，如何获取命令的退出码？如果这不可能，有没有办法在外部终端中运行命令（使用类似child_process.spawnSync()）并获取退出代码？

你可以这样做

const { spawn } = require('child_process');
const ls = spawn('ls', ['-lh', '/usr']);

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

ls.on('close', (code) => {
  console.log(`child process close all stdio with code ${code}`);
});

ls.on('exit', (code) => {
  console.log(`child process exited with code ${code}`);
});
