需要帮助通过Powershell创建基于文件名的文件夹

Question

我有过

\\192.168.1.2\Video\PodCasts\MyPodcast S01E01.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S01E02.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S01E02.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S02E01.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S02E02.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S02E03.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S03E01.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S03E02.mp4
\\192.168.1.2\Video\PodCasts\MyPodcast S03E03.mp4

我想创造

\\192.168.1.2\Video\PodCasts\Podcasts S01
\\192.168.1.2\Video\PodCasts\Podcasts S02
\\192.168.1.2\Video\PodCasts\Podcasts S03

我有一个PS脚本来创建文件夹并在其中移动文件。

到目前为止

$Show = Read-Host "Show"

cd "\\192.168.1.90\video\$Show"

Get-ChildItem -Filter "$Show S*.*" -File | ForEach-Object {
$series = $_.Name -replace '.*(S\d{2}).*', '$1'

# create the target path inside the same directory and create if needed
$destination = Join-Path -Path $_.DirectoryName -ChildPath $series
if (!(Test-Path -Path $destination -PathType Container)) {
    $null = New-Item -Path $destination -ItemType Directory
}
# move the file to the new path
$_ | Move-Item -Destination $destination -Force
}

这行得通

\192.168.1.2\视频\播客\S01\MyPodcast S01E01.mp4

我想调整一下

\192.168.1.2\视频\播客\MyPodcast S01\MyPodcast S01E01.mp4

我看不出$destination在哪里可以调整它

首先，永远不要运行破坏性的(新建，创建，重命名，移动，删除，更新，清除.)没有验证步骤的代码。

这就是你想要的吗？

Clear-Host

    'D:\PodCasts\MyPodcast S01E02.mp4',

) | 
ForEach {
    $SourceFolder      = [regex]::matches($PSItem, '.*\\PodCasts').Value
    $DestinationFolder = [regex]::matches($PSItem, 'S0\d').Value

    If (Test-Path -Path "$SourceFolder\$DestinationFolder")
    {
        Write-Verbose -Message  "Processing $SourceFolder\$DestinationFolder" -verbose
        Move-Item -Path $PSItem -Destination $destinationFolder -WhatIf
    }
    Else
    {
        Write-Warning -Message "

        New-Item $DestinationFolder -ItemType Directory -WhatIf
        Move-Item -Path $PSItem -Destination $destinationFolder -WhatIf
    }
}
