## [launchd](https://launchd.info/)
一个统一的开源服务管理框架，用于启动、停止和管理守护进程、应用程序、进程和脚本。由 Apple 的 Dave Zarzycki 编写和设计，它随 Mac OS X Tiger 引入并获得许可Apache 许可证。

## Daemon vs Agent
launchd 区分代理和守护进程。主要区别在于，代理代表登录用户运行，而守护进程代表根用户或您使用 UserName 键指定的任何用户运行。只有代理可以访问 macOS GUI。

## Job
根据它的存储位置，它将被视为守护进程或代理。

对操作系统操作至关重要的作业定义存储在 ```/System/Library``` 下。您永远不需要在这些目录中创建守护进程或代理。与每个用户相关的第三方定义存储在 ```/Library``` 下。特定用户的作业定义存储在相应用户的 ```Library``` 目录下。

| Type | Location | Run on behalf of |
| ---- | -------- | ---------------- |
| User Agents    | ~/Library/LaunchAgents        | Currently logged in user |
| Global Agents  | /Library/LaunchAgents         | Currently logged in user |
| Global Daemons | /Library/LaunchDaemons        | root or the user specified with the key ```UserName``` |
| System Agents  | /System/Library/LaunchAgents  | Currently logged in user |
| System Daemons | /System/Library/LaunchDaemons | root or the user specified with the key ```UserName``` |

## find 操作

sudo find ~/Library/LaunchAgents \
    /Library/LaunchAgents \

    /Library/LaunchAgents \
