Powershell-將目錄路徑列表傳遞到FOR Loop-將結果輸出到CSV

Question

下面的代碼有效。 與其手動指定路徑，我不希望從csv文件E：\\ Data \\ paths.csv中傳遞值列表，然后為每個處理的路徑輸出單獨的csv文件，並顯示該目錄的$ Depth ......

$StartLevel = 0 # 0 = include base folder, 1 = sub-folders only, 2 = start at 2nd level
$Depth = 10      # How many levels deep to scan
$Path = "E:\Data\MyPath"     # starting path

For ($i=$StartLevel; $i -le $Depth; $i++) {
$Levels = "\*" * $i
(Resolve-Path $Path$Levels).ProviderPath | Get-Item | Where PsIsContainer |
Select FullName
}

謝謝，菲爾

我假設您想要以下內容：

# Create sample input CSV
@"
Path,StartLevel,Depth
"E:\Data\MyPath",0,10
"@ > PathSpecs.csv

# Loop over each input CSV row (object with properties
# .Path, .StartLevel, and .Depth)
foreach ($pathSpec in Import-Csv PathSpecs.csv) {    
    & { For ([int] $i=$pathSpec.StartLevel; $i -le $pathSpec.Depth; $i++) {
      $Levels = "\*" * $i
      Resolve-Path "$($pathSpec.Path)$Levels" | Get-Item | Where PsIsContainer |
          Select FullName  
    } } | # Export paths to a CSV file named "Path-<input-path-with-punct-stripped>.csv"
    Export-Csv -NoTypeInformation "Path-$($pathSpec.Path -replace '[^\p{L}0-9]+', '_').csv"
}

請注意，您對子樹中子目錄的廣度優先枚舉的方法有效，但是對於大型子樹，它的速度將非常慢。
