 1 | # launchd with networkchange
 2 | 
 3 | A tool with shell script and launchd to trigger actions whenever a Mac's network information is changed.
 4 | 
 5 | [[简体中文版使用说明] 请点击这里](https://github.com/Jeff2Ma/launchd-with-networkchange/blob/master/readme.zh.md)
 6 | 
 7 | ## Introduction
 8 | 
 9 | This repo is an easy way to deal with contexts like:
10 | 
11 | > At workplace, your Mac Device has to make some settings such as change proxy address, set specical pac file, open some apps and so on. While at home your have change it again to others.
12 | 
13 | With the help of [launchd](https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLaunchdJobs.html), those operations can be automated. And that's what this repo do! It is fast, easy and safe.
14 | 
15 | ## Features
16 | 
17 | - Easy to install and uninstall.
18 | 
19 | - Password of your system account will be saved in keychain safely.
20 | 
21 | - Add example so that your can easily change the code according to your conditions.
22 | 
23 | ## How to start
24 | 
25 | ```bash
26 | $ git clone https://github.com/Jeff2Ma/launchd-with-networkchange
27 | 
28 | $ cd launchd-with-networkchange
29 | 
30 | $ python install.py
31 | ```
32 | Then input the info when is asked.
33 | 
34 | ![](_screenshots/install.png)
35 | 
36 | After that, please edit the code in `example.sh ` according to your conditions.
37 | 
38 | When your Mac's network change, a notification will show when it run shell script with success.
39 | 
40 | ![](_screenshots/notice.png)
41 | 
42 | ## Notices
43 | 
44 | 1) When the first run of the script, system will ask you like:
45 | 
46 | ![](_screenshots/first.png)
47 | 
48 | Remember to choose `Always Allow`.
49 | 
50 | 2）you can make a  `example.sh` copy one and rename it to `dynamic.sh`, it will be run instead of `example.sh`[see how it work](https://github.com/Jeff2Ma/launchd-with-networkchange/blob/master/_demo/_run.applescript#L23-L29).
51 | 
52 | 3) If you want to uninstall it, you can run `python install.py uninstall`.
53 | 
54 | 4) Check `/var/log/system.log` if you are having issues with `plist`.
55 |

  1 | # launchd with networkchange
  2 | 
  3 | 一个借助`launchd` 实现Mac 系统中网络变化时自动触发并运行指定脚本的工具。
  4 | 
  5 | ## 介绍
  6 | 
  7 | 本项目旨在通过自动化的方式解决如下场景:
  8 | 
  9 | > 在工作的时候，你的Mac 设备（特指MacBook、MacBook Air 或MacBook Pro）需要进行一些特殊的环境设置（比如修改代理地址，设置特殊的PAC 文件，需要专门打开某些应用，甚至是默认设备静音）。当下班回到家的时候，这些网络设置需要重新改变以适应你的家庭网络。然而第二天上班又要再次修改，如此往往复复。
 10 | 
 11 | 借助Mac 中的`launchd`（一个类似 crontab 的执行定时任务的东西），我们可以通过监控网络的变化（对于上面的场景具体而言是监控SSID 的变化）来自动触发运行指定脚本。本项目即是这么一个帮你快速配置这个`launchd`服务的一个工具。
 12 | 
 13 | **相关文章**：《[高效 Mac 人士必备：实现工作/家庭间网络环境切换的自动化](http://devework.com/mac-automatic-network.html)》
 14 | 
 15 | ## 原理
 16 | 
 17 | 在Mac 上，当网络有变化的时候(如关闭/开启WiFi，连接到不同SSID 等)，`/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist`这个文件就会有变化。因此借助`launchd`服务中的`WatchPaths`特征，就可以实现监控到文件变化的时候执行指定的脚本文件。
 18 | 
 19 | ## 特色
 20 | 
 21 | 本工具具有如下特色：
 22 | 
 23 | - 快速帮你进行配置`launchd`服务，免除繁琐的步骤，同时当你不喜欢的时候可以很方便地卸载。
 24 | 
 25 | - 因为涉及到网络变动的操作，所以需要用户权限。本工具会将你的用户密码保存在keychain 中，提高安全性。
 26 | 
 27 | - 提供了一个脚本文件(`example.sh`)，里面的代码可以方便按照个人需求进行改写。
 28 | 
 29 | ## 使用方法
 30 | 
 31 | ```bash
 32 | $ git clone https://github.com/Jeff2Ma/launchd-with-networkchange
 33 | 
 34 | $ cd launchd-with-networkchange
 35 | 
 36 | $ python install.py
 37 | ```
 38 | 按照说明输入用户名及密码。
 39 | 
 40 | ![](_screenshots/install.png)
 41 | 
 42 | 如上，成功完成后请根据个人实际情况改写`example.sh`的代码。
 43 | 
 44 | 网络变化的时候shell 文件就会自动运行，运行成功则会右上角提示如下：
 45 | 
 46 | ![](_screenshots/notice2.png)
 47 | 
 48 | ## 提示
 49 | 
 50 | 1) 完成上面的步骤之后，首次自动运行脚本的时候系统会弹窗如下:
 51 | 
 52 | ![](_screenshots/first.png)
 53 | 
 54 | 请选择“**始终允许**”按钮。
 55 | 
 56 | 2) 如果需要卸载已经生成的`launchd`服务，执行`python install.py uninstall`即可。
 57 | 
 58 | ## 自定义代码
 59 | 
 60 | 以下是一些可能用到的Shell 代码帮助你根据个人实际需求定制运行的Shell 基本文件。
 61 | 
 62 | 提示：你可以将`example.sh`文件复制一份重命名为`dynamic.sh`，直接在`dynamic.sh`上改写代码，两文件同时存在的时候会优先运行`dynamic.sh`（实现方式在[此处源代码](https://github.com/Jeff2Ma/launchd-with-networkchange/blob/master/_demo/_run.applescript#L23-L29)）。
 63 | 
 64 | ### 设置PAC 文件路径
 65 | 
 66 | ```bash
 67 | /usr/sbin/networksetup -setautoproxyurl Wi-Fi http://example.com/proxy.pac
 68 | ```
 69 | 
 70 | ### 运行或关闭某些APP
 71 | 
 72 | 本质上是调用 applescript 命令
 73 | 
 74 | ```bash
 75 | osascript <<EOD
 76 |     tell application "RTX"
 77 | 	    run
 78 |     end tell
 79 |     tell application "Proxifier"
 80 |         run
 81 |     end tell
 82 |     tell application "ShadowsocksX"
 83 |         quit
 84 |     end tell
 85 | EOD
 86 | ```
 87 | 
 88 | ### 清空DNS 服务器
 89 | 
 90 | ```bash
 91 | /usr/sbin/networksetup -setdnsservers Wi-Fi Empty
 92 | ```
 93 | 
 94 | ### kill 掉某进程
 95 | 
 96 | ```bash
 97 | ps -ef | grep Proxifier | awk '{print $2}' | xargs kill
 98 | ```
 99 | 
100 | ## launchd 常见指令
101 | 
102 | 一些常见指令参考，供个人调式之用：
103 | 
104 | - 检测plist 文件语法是否正确：
105 | 
106 | `plutil -lint com.devework.onnetworkchange.plist`
107 | 
108 | - 查看launchd 任务列表：`launchctl list`
109 | 
110 | - 查看launchd 任务列表（带过滤）：`launchctl list | grep 'deve'`
111 | 
112 | - 开启/关闭某项任务（-w选项会将plist文件中无效的key覆盖掉）：
113 | 
114 | ```bash
115 | launchctl load -w ~/Library/LaunchAgents/com.devework.onnetworkchange.plist
116 | 
117 | launchctl unload ~/Library/LaunchAgents/com.devework.onnetworkchange.plist
118 | ```
119 | 
120 | - 立刻执行某项任务（用于测试）：
121 | 
122 | `launchctl start com.devework.onnetworkchange`
123 | 
124 | - 停止执行任务：`launchctl stop com.devework.onnetworkchange`
125 |
