powershell - 目录列表递归父子内

Question

我想使用 -recurse 获取目录列表，但要显示父目录下的子目录。

这是我尝试过的:

Get-ChildItem -Directory -Depth 3 | Select-Object Fullname

结果首先显示顶级目录，然后是 2 级目录，然后是 3 级目录

例子:

C:\Users\Moshe\onedrive\pictures\35mm_Film    (has no sub directories)
C:\Users\Moshe\onedrive\pictures\Camera imports
C:\Users\Moshe\onedrive\pictures\Camera Roll

只有那时

C:\Users\Moshe\onedrive\pictures\Camera imports\Folder1
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder2
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder3

然后

C:\Users\Moshe\onedrive\pictures\Camera Roll\2014
C:\Users\Moshe\onedrive\pictures\Camera Roll\2016

我想得到显示父目录和子目录正下方的列表

例如:

C:\Users\Moshe\onedrive\pictures\35mm_Film    (has no sub directories)
C:\Users\Moshe\onedrive\pictures\Camera imports
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder1
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder2
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder3
C:\Users\Moshe\onedrive\pictures\Camera Roll
C:\Users\Moshe\onedrive\pictures\Camera Roll\2014
C:\Users\Moshe\onedrive\pictures\Camera Roll\2016

每个目录的文件数也很好，但不重要

例如:

C:\Users\Moshe\onedrive\pictures\35mm_Film 100
C:\Users\Moshe\onedrive\pictures\Camera imports 0 (no files in the parent)
C:\Users\Moshe\onedrive\pictures\Camera imports\Folder1  20

等等

如果您想在不需要事后排序的情况下执行此操作，解决方案可能会有点麻烦，您可以使用递归 function/script block或者如本例所示，使用 Stack<T> 作为可选，您可以使用 class :

class Tree {
    [int] $Depth
    [string] $Path
    [int] $FileCount
    hidden [IO.DirectoryInfo] $Instance

    Tree ([IO.DirectoryInfo] $Directory, [int] $Depth) {
        $this.Instance = $Directory
        $this.Path     = $Directory.FullName
        $this.Depth    = $Depth
        $this.CountFiles()
    }

    [IO.DirectoryInfo[]] EnumerateDirectories() {
        return $this.Instance.EnumerateDirectories()
    }

    [void] CountFiles() {
        $this.FileCount = $this.Instance.GetFiles().Count
    }
}


$stack = [Collections.Generic.Stack[Tree]]::new()
# define max Depth here
$maxDepth = 3
# initial path here
$path = 'C:\Users\Moshe\onedrive\pictures'
# define what you want to skip here
$attrToSkip = [IO.FileAttributes] 'Hidden'
$stack.Push([Tree]::new($path, 0))

while($stack.Count) {
    $folder = $stack.Pop()

    # this conditions stops the loop
    $reachedMaxDepth  = $folder.Depth -gt $maxDepth
    # this condition skips Hidden folders, remove it if you want to show all
    $isHiddenorSystem = $folder.Instance.Attributes -band $attrToSkip

    if($reachedMaxDepth -or $isHiddenorSystem) {
        continue
    }

    $folder

    foreach($i in $folder.EnumerateDirectories()) {
        $stack.Push([Tree]::new($i, $folder.Depth + 1))
    }
}
