Question

我正在学习PowerShell并且已经在Technet上看到了这个：

Test-Path -Path $DirectoryPath -PathType 'Leaf'

路径类型Leaf的含义是什么？

很清楚Container和Any路径类型是什么

Answer 1

如果您看到相同的PowerShell文档，则会很清楚。使用以下命令

Get-Help Test-Path -Full

如果您查看Test-Path支持的所有参数的说明，您会看到-PathType参数，其中包含

 -PathType <TestPathType>
 Specifies the type of the final element in the path. This cmdlet returns $True if the element is of the
 specified type and $False if it is not. The acceptable values for this parameter are:

 - Container. An element that contains other elements, such as a directory or registry key. - Leaf. An element
 that does not contain other elements, such as a file. - Any. Either a container or a leaf. Tells whether the
 final element in the path is of a particular type.

 Required?                    false
 Position?                    named
 Default value                None
 Accept pipeline input?       False
 Accept wildcard characters?  false

所以-container指的是目录，文件夹或子文件夹，而leaf指的是文件。如果您需要更多帮助，也可以使用Get-Help Test-Path -Examples

来自Test-Path帮助：

-PathType <TestPathType>
    Specifies the type of the final element in the path. This cmdlet returns $True if the element is of the specified
    type and $False if it is not. The acceptable values for this parameter are:

    - Container. An element that contains other elements, such as a directory or registry key. - Leaf. An element that
    does not contain other elements, such as a file. - Any. Either a container or a leaf. Tells whether the final
    element in the path is of a particular type.

具体做法是：

-Leaf。不包含其他元素的元素，例如文件。

从控制台获取此信息的最简单方法是Get-Help Test-Path -Parameter PathType

Test-Path -Leaf意思
