在多个根文件夹中创建子文件夹需要批处理或 PowerShell 脚本

我有大量的根文件夹（非连续命名），我需要一个脚本来在每个根文件夹内创建一组重复的子文件夹，如下所示：

例子

- Root Folder 1
   - Sub Folder A
      - Sub Sub Folder 1
      - Sub Sub Folder 2
      - Sub Sub Folder 3
      - Sub Sub Folder 4
      - Sub Sub Folder 5
   - Sub Folder B
   - Sub Folder C

- Root Folder 2
   - Sub Folder A
      - Sub Sub Folder 1
      - Sub Sub Folder 2
      - Sub Sub Folder 3
      - Sub Sub Folder 4
      - Sub Sub Folder 5
   - Sub Folder B
   - Sub Folder C

...等等。

所有根文件夹的子文件夹和子子文件夹的命名都是一致的，但是根文件夹名称会有所不同。

我能够通过以下方式使用 TXT 文件的输出在 D:\TEMP 目录中创建根文件夹：

for /F "usebackq delims=" %i in (FolderNames.txt) do md "%i"

我还可以通过一系列 PowerShell 命令在每个根文件夹中创建第一级子文件夹：

$folders = get-childitem "C:\TEMP\WORKING\FOLDERS"
foreach ($folder in $folders ) {
        New-Item -Name "Daily Completion Paperwork" -Path $folder.FullName -ItemType Directory -verbose;
        New-Item -Name "Final Completion Documents" -Path $folder.FullName -ItemType Directory -verbose;
        New-Item -Name "Site Documents" -Path $folder.FullName -ItemType Directory -verbose
}

这给了我：

- Root Folder 1
   - Sub Folder A
   - Sub Folder B
   - Sub Folder C

- Root Folder 2
   - Sub Folder A
   - Sub Folder B
   - Sub Folder C

我正在努力的是一个单独的命令 - 或者一个嵌套的命令 - 它将创建子文件夹 A 内的 5 个“子子文件夹”：

例子

- Root Folder 1
   - Sub Folder A
      - Sub Sub Folder 1
      - Sub Sub Folder 2
      - Sub Sub Folder 3
      - Sub Sub Folder 4
      - Sub Sub Folder 5

- Root Folder 2
   - Sub Folder A
      - Sub Sub Folder 1
      - Sub Sub Folder 2
      - Sub Sub Folder 3
      - Sub Sub Folder 4
      - Sub Sub Folder 5

不幸的是，这涉及到一个我无法确定的嵌套级别；到目前为止，我只是在里面创建了“子子文件夹”全部文件夹，这会造成更大的问题。

非常感谢有关如何修改我现有的 PowerShell 命令的任何建议！

对于这个特定的例子，我将创建一个辅助函数来按照您的需要创建每个文件夹结构。

像这样：

function New-FolderTree {
    [CmdletBinding()]
    Param(
        [Parameter(Mandatory = $true, Position = 0, ValueFromPipeline = $true)]
        [string]$Rootfolder,
        [string]$LevelOneName,     # name pattern for level 1 subfolders 
        [string]$LevelTwoName,     # name pattern for level 2 subfolders 
        [int]$LevelOneCount,       # howmany level 1 subfolders 
        [int]$LevelTwoCount        # howmany level 2 subfolders 
    )
    # step 1: create the rootfolder including the level one subfolders
    for ($i = 1; $i -le $LevelOneCount; $i++) {
        # LevelOne foldernames get a suffix of _A, _B, _C, etc.
        $path = Join-Path -Path $Rootfolder -ChildPath ('{0}_{1}' -f $LevelOneName, [char](64 + $i))
        if (!(Test-Path -Path $path -PathType Container)) {
            $null = New-Item -Path $path -ItemType Directory
        }
    }
    # step 2: create all level 2 subfolders in the first level 1 subfolder
    $subfolderA = Join-Path -Path $Rootfolder -ChildPath ($LevelOneName + '_A')
    for ($i = 1; $i -le $LevelTwoCount; $i++) {
        # LevelTwo foldernames get a suffix of _1, _2, _3, etc.
        $path = Join-Path -Path $subfolderA -ChildPath ('{0}_{1}' -f $LevelTwoName, $i)
        if (!(Test-Path -Path $path -PathType Container)) {
            $null = New-Item -Path $path -ItemType Directory
        }
    }
}

使用该功能，您可以快速创建每个文件夹结构

New-FolderTree -Rootfolder 'D:\RootFolder1' -LevelOneName 'SubFolder' -LevelOneCount 3 -LevelTwoName 'SubSubFolder' -LevelTwoCount 5
New-FolderTree -Rootfolder 'D:\RootFolder2' -LevelOneName 'SubFolder' -LevelOneCount 3 -LevelTwoName 'SubSubFolder' -LevelTwoCount 5

如果所有子文件夹都有相同的子子文件夹，则只需要嵌套 ForEach。溅射使代码更具可读性：

$Level1 = 'Daily Completion Paperwork',
          'Final Completion Documents',
          'Site Documents'
$Level2 = 1..5

 Get-ChildItem -Directory "C:\TEMP\WORKING\FOLDERS"| ForEach{
   $Splat =@{
      'Path'     = $_.FullName
      'ItemType' = 'Directory'
   }
   $Level1 | FOrEach{
      $Splat2 = @{
         'Path'     = (New-Item @Splat -Name $_).FullName
         'ItemType' = 'Directory'
      }

      $Level2 | ForEach{
         New-Item @Splat2 -Name $_ | Out-Null
      }
   }
}

尽管有 PowerShell。

最佳实践是，在操作系统文件系统上，避免在文件、文件夹和变量名称中使用空格。如果你这样做，你只会自找麻烦。始终使用下划线作为分隔符，或使用 CamelCasedNames 等，以免出现不必要的麻烦、挫败感和烦恼。

一个非常粗略的简单步骤，可以为您的用例提供更多的动态，可能是这样的（当然，修改到您想要的深度 - 如果您希望它真正创建东西，请删除-WhatIf。）：

# Using a single nested loop
Clear-Host
# Pass in a defined root folder array list to create root folders.
1..3 |
ForEach {
    "Creating new folder root named RootFolder$PSItem"
    New-Item -Path 'D:\Temp' -ItemType Directory -Name "RootFolder$PSItem" -WhatIf
    $RootFolderPath = "D:\Temp\RootFolder$PSItem"

    # Ask for a end boundary for sub folder array list
    $FolderCount = Read-Host -Prompt "
    For the new rootFolder $RootFolderPath, how many sub folders do you need.
    Enter a number." 

    # Pass in a defined root folder araay list to crete child folders.
    1..$FolderCount | 
    ForEach {
        "Using a sub folder count of $FolderCount
        Creating sub folder 1 - SubFolder$FolderCount"

        New-Item -Path $RootFolderPath -ItemType Directory -Name "SubFolderr$PSitem" -WhatIf
    }

    "`n"
    '*'*60
    "*** Finished creating scaffold for $RootFolderPath ***"
    '*'*60 
    "`n"
}
