Run Shell
SkillDocs & knowledgeLets your agent run shell commands to execute scripts, install packages, create directories, and manage system processes.
Instructions available. Your AI can read the instructions. Execution depends on the setup they require.
Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.
Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.
Then ask your AI: use the Run Shell skill
About this skill
Execute shell commands for system operations, directory creation, and script execution. When you need to run system commands, execute scripts, install packages, or manage processes. Note - if commands fail consecutively, try different approaches.

执行 Shell 命令。
Parameters
| 参数 | 类型 | 必填 | 说明 |
|---|---|---|---|
| command | string | 是 | 要执行的 Shell 命令 |
| cwd | string | 否 | 工作目录(可选) |
| timeout | integer | 否 | 超时时间(秒),默认 60,范围 10-600 |
Examples
列出目录:
{"command": "ls -la"}
安装依赖:
{"command": "pip install requests", "timeout": 300}
在指定目录执行:
{"command": "npm install", "cwd": "/path/to/project"}
Timeout Guidelines
- 简单命令: 30-60 秒
- 安装/下载: 300 秒
- 长时间任务: 根据需要设置更长时间
Windows PowerShell 指引(重要)
转义保护
系统会自动将 PowerShell 命令通过 -EncodedCommand(Base64 UTF-16LE)编码执行,
避免 cmd.exe → PowerShell 的多层引号/特殊字符转义破坏。直接传入 PowerShell 命令即可。
何时使用 PowerShell vs Python 脚本
| 场景 | 推荐方式 | 原因 |
|---|---|---|
| 简单系统查询(进程/服务/文件列表) | PowerShell cmdlet | Get-Process, Get-ChildItem 等一行搞定 |
| 复杂文本处理(正则、URL 提取、HTML/JSON 解析) | Python 脚本 | 避免 PowerShell 正则 one-liner 的复杂性 |
| 批量文件操作(重命名、过滤、转换) | Python 脚本 | 更可靠,不受 PowerShell 管道转义影响 |
| 网络下载/HTTP 请求 | Python 脚本 | requests/urllib 比 Invoke-WebRequest 更灵活 |
推荐的 Python 脚本模式
对于复杂文本处理任务,务必使用 write_file + run_shell 组合:
步骤 1: write_file 写入 data/temp/task_xxx.py
步骤 2: run_shell "python data/temp/task_xxx.py"
禁止:在 run_shell 中写包含复杂正则的 PowerShell one-liner,例如:
# 禁止这种写法
powershell -Command "Get-Content file.html | Select-String -Pattern '(?<=src=\")[^\"]+' | ForEach-Object { $_.Matches.Value } | Sort-Object -Unique | Out-File urls.txt"
应改为写 Python 脚本:
import re
from pathlib import Path
html = Path("file.html").read_text(encoding="utf-8")
urls = sorted(set(re.findall(r'src="([^"]+)"', html)))
Path("urls.txt").write_text("\n".join(urls), encoding="utf-8")
Notes
- Windows 使用 PowerShell/cmd 命令(自动 EncodedCommand 编码)
- Linux/Mac 使用 bash 命令
- 如果命令连续失败,请尝试不同的命令或方法
- 失败时可调用
