如何让 -Depth 开关在脚本中工作？

Question

我试图限制此脚本的递归深度，该脚本生成文件夹列表、关联的安全组以及每个组的成员。我正在使用 PowerShell 5.1。

我尝试在第 18 行添加 -Depth 3（如下所示），但我仍然获得了所有级别。当我运行脚本时，我尝试在命令行上添加 -Depth 3，但那是错误的。

这是我用来运行脚本的命令：

./Get_folder_acls_depth_test.ps1 -Path I:\dir_name -Recurse | Export-Csv c:\temp\dir_name.csv

我也试过了，但出现错误：

./Get_folder_acls_depth_test.ps1 -Path I:\dir_name -Recurse -Depth 3 | Export-Csv c:\temp\dir_name.csv

[CmdletBinding()]
Param(
    [ValidateScript({Test-Path $_ -PathType Container})]
    [Parameter(Mandatory=$true)]
    [string]$Path,
    [switch]$Recurse
)

Write-Verbose "$(Get-Date): Script begins!"
Write-Verbose "Getting domain name..."
$Domain = (Get-ADDomain).NetBIOSName

Write-Verbose "Getting ACLs for folder $Path"

if ($Recurse) {
    Write-Verbose "...and all sub-folders"
    Write-Verbose "Gathering all folder names, this could take a long time on bigger folder trees..."
    $Folders = Get-ChildItem -Path $Path -Directory -Recurse -Depth 3
} else {
    $Folders = Get-Item -Path $Path
}

Write-Verbose "Gathering ACL's for $($Folders.Count) folders..."
foreach ($Folder in $Folders) {
    Write-Verbose "Working on $($Folder.FullName)..."
    $ACLs = Get-Acl $Folder.FullName | ForEach-Object { $_.Access }
    foreach ($ACL in $ACLs) {
        if ($ACL.IdentityReference -match "\") {
            if ($ACL.IdentityReference.Value.Split("\")[0].ToUpper() -eq $Domain.ToUpper()) {
                $Name = $ACL.IdentityReference.Value.Split("\")[1]
                if ((Get-ADObject -Filter 'SamAccountName -eq $Name').ObjectClass -eq "group") {
                    foreach ($User in (Get-ADGroupMember $Name -Recursive | Select -ExpandProperty Name)) {
                        $Result = New-Object PSObject -Property @{
                            Path = $Folder.Fullname
                            Group = $Name
                            User = $User
                            FileSystemRights = $ACL.FileSystemRights
                            AccessControlType = $ACL.AccessControlType
                            Inherited = $ACL.IsInherited
                        }
                        $Result | Select Path,Group,User,FileSystemRights
                    }
                } else {
                    $Result = New-Object PSObject -Property @{
                        Path = $Folder.Fullname
                        Group = ""
                        User = Get-ADUser $Name | Select -ExpandProperty Name
                        FileSystemRights = $ACL.FileSystemRights
                        AccessControlType = $ACL.AccessControlType
                        Inherited = $ACL.IsInherited
                    }
                    $Result | Select Path,Group,User,FileSystemRights
                }
            } else {
                $Result = New-Object PSObject -Property @{
                    Path = $Folder.Fullname
                    Group = ""
                    User = $ACL.IdentityReference.Value
                    FileSystemRights = $ACL.FileSystemRights
                    AccessControlType = $ACL.AccessControlType
                    Inherited = $ACL.IsInherited
                }
                $Result | Select Path,Group,User,FileSystemRights
            }
        }
    }
}
Write-Verbose "$(Get-Date): Script completed!"

该脚本适用于所有级别，我只想将其限制为 2-4 级。

我测试了你的脚本，以检查你的 if/else 语句是否正常工作，我得到了正确的结果：

function Test-Recurse {
    Param(
        [ValidateScript( {Test-Path $_ -PathType Container})]
        [Parameter(Mandatory = $true)]
        [string]$Path,
        [switch]$Recurse
    )

    begin {
        Write-Verbose "$(Get-Date): Script begins!"
        $folders = $null
    }

    process {
        if ($Recurse) {
            Write-Output -InputObject "Recurse has been selected"
            $folders = Get-ChildItem -Path $Path -Directory -Recurse -Depth 3
        }
        else {
            Write-Output -InputObject "Recurse has NOT been selected"
            $folders = Get-ChildItem -Path $Path -Directory
        }
    }

    end {
        return $folders.fullName
    }
}

PS C:\GitHub\Guyver1wales\PowerShell>

-深度从0开始所以-深度3会显示4个子文件夹： C:\programdata\razer\Synapse\ProductUpdates\Uninstallers\RazerDeathAdder3500Config

0 = \突触

1 = \ProductsUpdates

2 = \卸载程序

3 = \RazerDeathAdder3500Config
