Question

我想这样做，以便每天午夜删除 Mac 上标准用户帐户的文档和桌面文件夹的内容。我怎样才能做到这一点？

Answer 1

~/Library/LaunchAgents/me.lri.clear.desktop.and.documents.plist

<?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>me.lri.clear.desktop.and.documents</string>
    <key>ProgramArguments</key>
    <array>
        <string>osascript</string>
        <string>-e</string>
        <string>say "lol"</string>
        <!-- <string>tell application "Finder"
        move items of desktop to trash
        move items of (path to documents folder) to trash
        end tell</string> -->
    </array>
    <key>StartInterval</key>
    <integer>5</integer> <!-- every 5 seconds -->
    <!-- <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>23</integer>
        <key>Minute</key>
        <integer>0</integer>
    </dict> --> 
    </dict>
</plist>

代理将在注销并重新登录后加载，或者在运行launchctl load ~/Library/LaunchAgents/me.lri.clear.desktop_and.documents.plist.

查看man launchctl和man launchd.plist了解更多信息。

另一种选择是将这样的内容添加到您的 crontab 中：

0 0 0 * * osascript -e 'tell app "Finder"' -e 'move items of desktop to trash' -e 'move items of (path to documents folder) to trash' -e 'end'

（您可以将其另存为~/.crontab，然后运行crontab ~/.crontab）
