如何设置 AppleScript 在给定文件被修改时运行？

on idle
    set filePath to "路径/到/你的/文件.txt"
    set modificationDate to (do shell script "stat -f %m " & quoted form of POSIX path of filePath)
    if modificationDate is not equal to my lastModificationDate then
        display dialog "文件已被修改！"
        set my lastModificationDate to modificationDate
    end if
    return 1 -- 每秒钟检查一次文件是否被修改
end idle

 ```xml

 <?xml version="1.0" encoding="UTF-8"?>

 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

 <plist version="1.0">

 <dict>

     <key>Label</key>

     <string>com.example.filewatcher</string>

     <key>ProgramArguments</key>

     <array>

         <string>osascript</string>

         <string>/路径/到/你的/脚本文件.scpt</string>

     </array>

     <key>WatchPaths</key>

     <array>

         <string>/路径/到/你的/文件.txt</string>

     </array>

 </dict>

 </plist>

 ```

 将 `<string>/路径/到/你的/脚本文件.scpt</string>` 替换为你保存的 AppleScript 脚本文件的路径，将 `<string>/路径/到/你的/文件.txt</string>` 替换为你要监视的文件的路径。

 ```bash

 launchctl load ~/Library/LaunchAgents/com.example.filewatcher.plist

 ```

 这将启动文件监视。
