介绍 powershell 的基础使用

环境构建

多年来，PowerShell 已有很多版本发布。 最初，Windows PowerShell 是在 最初 .NET Framework 基础之上构建而成， 仅适用于 Windows 系统。 在最新版本中，PowerShell 使用 新版 .NET Core 3.1 作为运行时。 PowerShell 在Windows、macOS 和 Linux平台上运行。

基础知识整理

• 查看版本$PSVersionTable.PSVersion

• 特性介绍

  • 命令行输入命令的关键字使用tab和shift+tab实现自动代码提示

• 语法介绍

  • 实参均支持通配符：*等其他符号

    #具体的参考
    $help about_wildcards
    

  • 接受参数均以 -开始

    $get-help get-service -full
    

  • -ShowWindow用于单独弹窗显示帮助内容

  • get-alias显示内置的函数 abbr 写法

  • 使用分号;执行多个语句命令

    $cls ; cd E:
    

• 查看帮助文档

  #help,get-help都是可以的
  $help
  
  #更方便并且可以支持搜索
  #支持搜索的通配符例如：*
  $get-help xx*xx*
  #查看帮助文档信息
  $get-help -full/-detailed/-examples
  
  #在新的窗口里查看文档 [ShowWindow]
  $get-help get-service -ShowWindow
  
  #查看about的文档基于powershell的构建信息
  $help about_* #匹配查询所有的主题
  $help about_xxxx#查看主题内容
  

其他命令操作

• 管道pipline 操作符|

  #实现简单的对象引用
  
  #导出信息到csv
  $get-help get-service M* | export service.csv
  

• -whatif获取执行命令产生的结果,和管道|一起使用，作为执行命令时的提示

  $get-service M* -whatif/-confirm
