缘由：

简单记录一下如何在Windows/macOS系统上进行软件的安装和卸载（主要是想记录命令行下的安装，为后面的静默安装/编写小白也容易理解的安装教程/工具做准备，可视化的点击交互式安装不是重点，一笔带过即可），方便后面参考。

安装

Windows-图形化界面

鼠标双击（然后跟着指示操作即可）
鼠标右键-以管理员身份运行(A)

Windows-命令行终端

setup.exe

# 如果路径不太好输入的话，可以先打开一个CMD终端，然后用鼠标把软件拖动到终端上就会有路径了
> "C:\SomeFolder\setup.exe"
> "C:\SomeFolder\setup.exe" /VERYSILENT /SUPPRESSMSGBOXES /NORESTART

setup.msi

> msiexec /i C:\setup.msi /qn
> msiexec /i C:\setup.msi /qn /norestart

选项说明

# msiexec

/quiet, /q, qn	Fully silent mode (静默安装)
/passive	Unattended mode, shows progress bar only.
/norestart	Do not restart the system after the installation
/forcerestart	Restart the system after installation is complete
/log, /l	Enable Logging


# setup.exe

/SILENT	Runs the installer in silent mode (The progress window is displayed)
/VERYSILENT	(静默安装)Very silent mode. No windows are displayed.
/SUPPRESSMSGBOXES	Suppress message boxes. Only has an effect when combined with ‘/SILENT’ and ‘/VERYSILENT’.
/NOCANCEL	Disables cancelling the installation process.
/NORESTART	Prevents installer from restarting the system even if it’s necessary.
/DIR="x:\dirname"	Overrides the default install directory.

macOS-图形化界面

鼠标双击（然后跟着指示操作即可）

macOS-命令行终端

$ sudo installer -pkg /path/to/filename.pkg -target /

卸载

Windows-图形化界面

Windows控制面板 – 卸载程序 – 选定应用右键卸载 #Windows7
Windows设置 – 应用和功能 – 选定应用进行卸载 #Windows10
有很多应用都有此功能，在此不一一列举了

Windows-命令行终端

// Silently uninstall the msi package:
> msiexec /x C:\setup.msi /qn

// Silently uninstall the msi package by the product code:
> msiexec /x {XXXXXXXX-9215-4780-AAC6-01FD101DC931} /qn

// wmi
> wmic product where name="my_product_name" call uninstall

// powershell
powershell> (Get-WmiObject -Query "SELECT * FROM Win32_Product WHERE Name like '%Partial Name%'").uninstall()

HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall
HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\

Every program that properly installs itself according to Microsoft’s guidelines makes a registry entry in HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall. Usually, the key for the program will be its GUID, or else the name of the program. Within that key will be an entry called UninstallString. This contains the command to execute to uninstall the program.

If you already know ahead of time what you will be uninstalling, it should be easy enough to just put that in your batch file. It gets tricky when you try to automate that process though. You can use the reg command to get data from the registry, but it returns a lot of text around the actual value of a given key, making it hard to use. You may want to experiment with using VBscript or PowerShell, as they have better options for getting data from the registry into a variable.

macOS-图形化界面

直接将app拖到废纸篓里就行
很多macOS应用，比如CleanMyMac

macOS-命令行终端

1. 简单的是直接删除特定的 .app 目录
2. 复杂的可能还有一些配置/文件存放在了其它目录需要一起删除才能完整地进行卸载
3. 对于有保活功能的软件来说，需要先杀掉相关进程然后同步删除相关目录，才能完成卸载

mdfind
lsof
