使用 Google zx 编写更优秀的 shell 脚本的综合指南——利用 JavaScript/TypeScript 来编写、调试或重构 zx 脚本(.mjs、.js、.ts 文件),执行 Shell 命令,管理进程管道以及配置 zx 选项。

openclaw-master-skills 是什么?

该技能是一个关于 Google zx 工具的中文综合指南,zx 是一个使用 JavaScript/TypeScript 编写 Shell 脚本的框架。它详细介绍了 zx 的核心概念,包括如何使用 tagged template literal `$` 安全地执行 Shell 命令,自动转义参数,并提供 ProcessPromise 和 ProcessOutput API 用于处理命令输出、错误和流。用户可以通过它了解如何并行执行任务、优雅地处理错误、进行流式管道操作,以及利用内置的 helpers(如 `cd`、`fetch`、`question`、`retry` 等)来简化常见脚本任务。此外,它还涵盖了 Shell 配置(支持 Bash、PowerShell)、预设配置、异步迭代和 Markdown 脚本触发等高级功能,帮助开发者提升脚本编写效率。此指南适用于 Claude Code、Cursor、Codex 等 AI 代理,当用户询问在 JavaScript 中运行 Shell 命令、将 Bash 脚本转换为 zx、或使用 zx CLI 时自动触发。技能内容基于其文档结构,提供了从快速入门到深入使用的完整路径,并链接了详细的 API、配置和 CLI 参考。

Zx — 用 JavaScript 编写更优秀的 Shell 脚本

概述

zx 是 Google 推出的工具,让你能用 JavaScript/TypeScript 编写 Shell 脚本。它封装了 child_process,自动转义参数,并提供合理的默认值 —— 让你在脚本中发挥 JavaScript 生态系统的全部威力。

#!/usr/bin/env zx

await $`cat package.json | grep name`

const branch = await $`git branch --show-current`
await $`dep deploy --branch=${branch}`

const name = 'foo & bar'
await $`mkdir /tmp/${name}`  // 无需引号 — 自动转义

Bash 擅长简单任务,但当脚本变得复杂时,一门完整的编程语言会很有帮助。zx 在 child_process 周围添加了便利的封装,自动转义参数,并提供合理的默认值。可以理解为:bash + JavaScript 合二为一。

触发条件

当用户询问关于在 JavaScript 中运行 Shell 命令、将 Bash 脚本转换为 zx、执行远程脚本、Markdown 脚本或 TypeScript Shell 脚本时,也会触发此技能。

快速开始

npm install zx

将脚本编写为 .mjs 文件(支持顶级 await)。添加 #!/usr/bin/env zx shebang 或通过 CLI 运行:

zx ./script.mjs           # 直接执行
npx zx ./script.mjs       # 通过 npx
node --import zx/globals  # 作为 Node.js 加载器

在 zx 脚本中,所有函数($, cd, fetch 等)都是全局可用的,无需导入。如需显式导入(以获取更好的 VS Code 自动补全):

import 'zx/globals'

核心概念

$`command` — 执行 Shell 命令

Tagged template literal 是 zx 的核心。${...} 中的所有内容都会被自动转义并加引号。

// 异步(标准方式)— 返回 ProcessPromise
const output = await $`ls -la`

// 同步变体 — 直接返回 ProcessOutput
const dir = $.sync`pwd`

// 数组会被展平
const flags = ['--oneline', '--decorate', '--color']
await $`git log ${flags}`

// 非零退出码会抛出 ProcessOutput
try {
  await $`exit 1`
} catch (p) {
  console.log(`Exit: ${p.exitCode}, Error: ${p.stderr}`)
}

使用 $({...}) 进行预设配置

创建具有预设选项的自定义 $ 实例——可链式调用和组合:

const $$ = $({ verbose: false, env: { NODE_ENV: 'production' } })
const pwd = $$.sync`pwd`

// 预设可链式调用
const $1 = $({ nothrow: true })
const $2 = $1({ sync: true })  // 同时应用 nothrow 和 sync

ProcessPromise 和 ProcessOutput

$`cmd`              ProcessPromise (继承 Promise)
  ├── .pipe()       流管道
  ├── .kill()       终止进程
  ├── .text()       以字符串形式输出
  ├── .json()       以解析后的 JSON 形式输出
  ├── .lines()      按行分割输出
  ├── .nothrow()    为此命令抑制错误
  ├── .quiet()      为此命令抑制输出
  ├── .timeout()    在指定时间后自动终止
  ├── .stdio()      配置 I/O
  ├── .exitCode     Promise<退出码>
  ├── .stdout       可读流
  ├── .stderr       可读流
  ├── .stdin        可写流
  ├── .pid / .cmd   进程元数据
  └── await → ProcessOutput
                ├── .stdout    string
                ├── .stderr    string
                ├── .exitCode  number
                ├── .signal    string|null
                ├── .text() / .json() / .lines() / .buffer() / .blob()
                └── .ok        boolean (当使用 nothrow 时)

决策树

编写 zx 脚本时,请遵循此决策树:

目标方法
运行一个命令await $`cmd`
同步运行$.sync`cmd`
管道输出.pipe($`next`) / .pipe('file.txt')
优雅地处理错误$({nothrow: true}) / .nothrow()
设置超时$({timeout: '30s'}) / .timeout('30s')
解析 JSON 输出(await $`cmd`).json()
实时流式处理for await (const line of $`cmd`)
失败时重试retry(5, () => $`cmd`)
用户提示question('Name: ')
进度指示器await spinner('Working...', () => $`cmd`)
更改目录cd('/path') 或 within(() => { $.cwd = '/tmp' })
临时文件/目录tmpfile() / tmpdir()
解析 CLI 参数argv.flag 或 minimist(process.argv.slice(2))
加载 .env 文件dotenv.config('.env')

编写高效的 zx 脚本

并行执行

const results = await Promise.all([
  $`sleep 1; echo 1`,
  $`sleep 2; echo 2`,
  $`sleep 3; echo 3`,
])

使用 nothrow 处理错误

$.nothrow = true

const repos = ['zx', 'webpod']
const clones = repos.map(n => $`git clone https://github.com/google/${n}`)

const results = await Promise.all(clones)
const errors = results.filter(o => !o.ok).map(o => o.stderr.trim())
console.log('Errors:', errors.join('\n'))

流管道

// 像 bash 管道一样链式调用命令
const greeting = await $`printf "hello"`
  .pipe($`awk '{printf $1", world!"}'`)
  .pipe($`tr '[a-z]' '[A-Z]'`)

// 管道到文件
await $`echo "Hello!"`.pipe('/tmp/output.txt')

// 实时输出到终端
await $`echo 1; sleep 1; echo 2; sleep 1; echo 3`.pipe(process.stdout)

流拆分与合并

// 将一个源拆分成多个消费者
const p = $`some-command`
const [o1, o2] = await Promise.all([
  p.pipe`log`,
  p.pipe`extract`,
])

// 合并多个源
const $h = $({ halt: true })
const p1 = $`echo foo`
const p2 = $h`echo a && sleep 0.1 && echo b`
const p3 = $h`echo c && sleep 0.1 && echo d`
const cat = $h`cat`
p1.pipe(cat); p2.pipe(cat); p3.pipe(cat)
await cat.run()

输出格式化

const p = $`echo '{"foo":"bar"}\nline2'`

await p.json()    // { foo: 'bar' }
await p.lines()   // ['{"foo":"bar"}', 'line2']
await p.text()    // '{"foo":"bar"}\nline2\n'

异步迭代

for await (const line of $`git log --oneline --max-count=5`) {
  console.log(line)
}

Shell 配置

zx 默认使用 bash。根据需要切换 Shell:

import { useBash, usePowerShell, usePwsh } from 'zx'

usePowerShell()  // PowerShell.exe
usePwsh()        // PowerShell v7+
useBash()        // 切回 bash

// 手动覆盖
$.shell = '/bin/zsh'

在 Windows 上,考虑使用 WSL 或 Git Bash 来支持 bash,或者通过 usePowerShell() 切换到 PowerShell。
