[Mac/Snow Leopard] launchctl - Mac OS X load/unload daemons or agents command

　　一般在Unix/Linux上，我們會透過 service 這指令來控制(啟用/停用)某些系統服務，在WIndows上也可以透過，"控制台->管理->服務及應用程式" 或 msconfig來達到同等效用。在我的雪豹被我養得愈來愈肥的情況下，該是停掉一些無三小路用的service的時候了。
　　詳細指令操作，請找男人: man launchctl
．Disable / Unload oooxxx:
sudo launchctl unload -w /System/Library/LaunchAgents/com.apple.oooxxx.plist
．Enable / Load oooxxx:
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.oooxxx.plist
．所有Daemons及Agents的擺放目錄如下:

man launchctl
~/Library/LaunchAgents         Per-user agents provided by the user.
/Library/LaunchAgents          Per-user agents provided by the administrator.
/Library/LaunchDaemons         System wide daemons provided by the administrator.
/System/Library/LaunchAgents   Mac OS X Per-user agents.
/System/Library/LaunchDaemons  Mac OS X System wide daemons.
