如何递归文件夹并显示相对文件夹路径？

这是一个简单的脚本：

$srcpth = "C:\Users\Mark\Desktop\dummy\"
$files = Get-ChildItem -Path $srcpth -File -Recurse 

foreach ($f in $files) {
    $filen = $f.Name
    $filesize = $f.Length
    Write-Output "$filen $filesize"
    }

这将正确循环遍历所有子文件夹C:\Users\Mark\Desktop\dummy并输出文件名和文件大小，但不会显示相对路径。如何解析相对路径？谢谢。

编辑：添加如下以澄清所需的输出：

例如，在C:\Users\Mark\Desktop\dummy是包含文件的子文件夹

C:\Users\Mark\Desktop\dummy\file00.txt
C:\Users\Mark\Desktop\dummy\folder01\file01_01.txt
C:\Users\Mark\Desktop\dummy\folder01\file01_02.txt
C:\Users\Mark\Desktop\dummy\folder01\file01_03.txt

C:\Users\Mark\Desktop\dummy\folder02\file02_01.txt
C:\Users\Mark\Desktop\dummy\folder02\file02_01.txt

C:\Users\Mark\Desktop\dummy\folder03\file03_01.txt
C:\Users\Mark\Desktop\dummy\folder03\file03_02.txt
C:\Users\Mark\Desktop\dummy\folder03\file03_03.txt
C:\Users\Mark\Desktop\dummy\folder03\file03_04.txt

上述代码的输出产生：

file00.txt 9
file01_01.txt 10
file01_02.txt 12
file01_03.txt 12
file02_01.txt 15
file02_01.txt 14
file03_01.txt 11
file03_02.txt 15
file03_03.txt 13
file03_04.txt 12

但我想要的是：

file00.txt 9
\folder01\file01_01.txt 10
\folder01\file01_02.txt 12
\folder01\file01_03.txt 12
\folder02\file02_01.txt 15
\folder02\file02_01.txt 14
\folder03\file03_01.txt 11
\folder03\file03_02.txt 15
\folder03\file03_03.txt 13
\folder03\file03_04.txt 12

前\，没有斜线，或者.\很好。

我建议你输出objects https://learn.microsoft.com/en-us/powershell/scripting/learn/deep-dives/everything-about-pscustomobject?view=powershell-7.2在任何情况下，您都可以使用以下方式获取相对路径，而不是像您现在所做的那样.SubString(..) https://learn.microsoft.com/en-us/dotnet/api/system.string.substring?view=net-6.0:

foreach ($f in Get-ChildItem -Path $srcpth -File -Recurse) {
    [pscustomobject]@{
        FileName     = $f.Name
        FileSize     = $f.Length
        RelativePath = $f.FullName.Substring($srcpth.Length + 1)
    }
}

或者如果你正在使用PowerShell核心，您可以访问.NET APIPath.GetRelativePath(String, String) https://learn.microsoft.com/en-us/dotnet/api/system.io.path.getrelativepath?view=net-6.0#system-io-path-getrelativepath(system-string-system-string):

foreach ($f in Get-ChildItem -Path $srcpth -File -Recurse) {
    [pscustomobject]@{
        FileName     = $f.Name
        FileSize     = $f.Length
        RelativePath = [IO.Path]::GetRelativePath($srcpth, $f.FullName)
    }
}

还有PathIntrinsics.NormalizeRelativePath(String, String) Method https://learn.microsoft.com/en-us/dotnet/api/system.management.automation.pathintrinsics.normalizerelativepath?view=powershellsdk-7.0.0Windows PowerShell 和 PowerShell Core 都可用，尽管这似乎有点矫枉过正：

$ExecutionContext.SessionState.Path.NormalizeRelativePath($f.FullName, $srcpth)
