假设我有一个自定义命令：

function Search-ForStringInFile($string)
{
        ls -Recurse | Select-String -Pattern "$string" -List | Select Path
}

而且我希望能够运行Get-Help Search-ForStringInFile或Get-Command Search-ForStringInFile获得命令功能的描述。

描述：在当前目录/下的所有文件中搜索关键字

我可以在function添加此文档时使用特殊的注释语法吗？

这称为基于注释的帮助。事实上，PowerShell ISE 有一个非常棒的代码片段，可以准确地完成您想做的事情。只需点击 Control+J 并选择“Cmdlet - 高级功能”来加载我将在下面提供的代码片段：

<#

   Short description
.DESCRIPTION
   Long description
.EXAMPLE

.EXAMPLE
   Another example of how to use this cmdlet
#>
function Verb-Noun
{
}

一旦您填写了上述每一项的值（请参阅此处的文档以了解所有可用字段）并按 F5，帮助将出现在您的函数中。

因此，要向您自己的 cmdlet 添加帮助，您只需在函数中粘贴相同的注释块即可。您可以将其放置在以下三个位置之一：

  • 在函数声明之前
  • 函数声明后(ewww)
  • 在你的功能结束时（不要被认为是，但选择这个选项在道德上是错误的）。

文档也在这里提供了每个已批准位置的示例。
