OSX脚本:禁止系统自动添加AppStore图标到用户Dock上

本脚本提供了一种方法来删除Dock程序默认自动添加的AppStore.app图标,适用于希望禁用此功能的企业环境。

这个脚本会删除Dock程序默认的自动添加App Store.app图标到用户Dock上的行为。

具体的操作使用参见脚本说明。

#!/bin/bash # ------------------------------------------------------------------------ # Removing App Store icon from User's Dock: # # Script name: RmAppStoreIcon.sh # # Copy Right: # Copy Right 2011 Tony Liu, all right reserved. # # Description: # If you don't want end user to have App Store icon on their Dock, this is right for you. # Why bother this? because most enterprise environment policies don't like people purchasing # stuff online, ie App Store. # # The system wide Dock icon is stored in the plist file: # /System/Library/CoreServices/Dock.app/Contents/Resources/English.lproj/default.plist # # This script needs PlistBuddy command line tools installed on your OS, which is included in most # of Apple packages. it's easy to be found anyway. Or pack commands in a installation package. # # You can use the following command to remove it: # plistbuddy -c "delete :persistent-apps:0" /System/Library/CoreServices/Dock.app/Contents/Resources/English.lproj/default.plist # # For newly login users, Dock.app will put the App Store icon on user's Dock automatically. # For logged in users, the App Store icon is already sits on their Dock. # To remove for all users, a the best practise example likes this: # removeSysAppStoreIcon # removeAllUserAppStoreIcon # # Another approch: removing the "App Store.app" from /Applications folder totally. # # For some situation, you may want end users to use it at home, but not in enterprise environment. # do the restriction within MCX or Workgroup Manager. # # History: # Initial: Tony 2011-06-20 # # ------------------------------------------------------------------------ # How to use these commands: # call removeAllUserAppStoreIcon to remove for all users # call removeUserAppStoreIcon USERNAME, to remove USERNAME user's App Store icon. # call removeSysAppStoreIcon to remove from system wide. # ------------------------------------------------------------------------ function RemoveAppStore { defaultPlist="$1" #currentSet=`plistbuddy -c "print :persistent-apps" $defaultPlist` #currentSet=${currentSet/////":"} index=0 while [ true ] do curAppIcon=`plistbuddy -c "print :persistent-apps:$index" $defaultPlist` echo "$index" "$curAppIcon" if [ -n "$curAppIcon" ]; then isAppStore=`echo $curAppIcon | grep "App Store"` if [ -n "$isAppStore" ]; then sudo plistbuddy -c "delete :persistent-apps:$index" $defaultPlist echo "Deleted App Store @ $index" break else let index=index+1 fi else break fi done } function removeSysAppStoreIcon { RemoveAppStore "/System/Library/CoreServices/Dock.app/Contents/Resources/English.lproj/default.plist" } function removeUserAppStoreIcon { RemoveAppStore "/Users/$1/Library/Preferences/com.apple.Dock.plist" } function removeAllUserAppStoreIcon { for aUser in `ls -1 /Users` do removeUserAppStoreIcon "$aUser" done } RemoveAppStore "/Users/schooladmin/Desktop/default.plist" exit 0

提供了基于BP(Back Propagation)神经网络结合PID(比例-积分-微分)控制策略的Simulink仿真模型。该模型旨在实现对杨艺所著论文《基于S函数的BP神经网络PID控制器及Simulink仿真》中的理论进行实践验证。在Matlab 2016b环境下开发,经过测试,确保能够正常运行,适合学习和研究神经网络在控制系统中的应用。 特点 集成BP神经网络:模型中集成了BP神经网络用于提升PID控制器的性能,使之能更好地适应复杂控制环境。 PID控制优化:利用神经网络的自学习能力,对传统的PID控制算法进行了智能调整,提高控制精度和稳定性。 S函数应用:展示了如何在Simulink中通过S函数嵌入MATLAB代码,实现BP神经网络的定制化逻辑。 兼容性说明:虽然开发于Matlab 2016b,但理论上兼容后续版本,可能会需要调整少量配置以适配不同版本的Matlab。 使用指南 环境要求:确保你的电脑上安装有Matlab 2016b或更高版本。 模型加载: 下载本仓库到本地。 在Matlab中打开.slx文件。 运行仿真: 调整模型参数前,请先熟悉各模块功能和输入输出设置。 运行整个模型,观察控制效果。 参数调整: 用户可以自由调节神经网络的层数、节点数以及PID控制器的参数,探索不同的控制性能。 学习和修改: 通过阅读模型中的注释和查阅相关文献,加深对BP神经网络与PID控制结合的理解。 如需修改S函数内的MATLAB代码,建议有一定的MATLAB编程基础。
