我的目标是编写一个 powershell 脚本，它将递归地检查文件服务器中是否存在任何“x”（插入天数）旧或更旧的目录。

我最初遇到了一些问题，我想我已经解决了大部分问题。我遇到的问题之一是 248 个字符的路径限制。我发现我在我的代码中实现了一个自定义函数来绕过这个限制。

最终结果是我想输出文件夹的路径和 LastAccessTime 并将信息导出到易于阅读的 csv 文件中。

目前一切正常，但由于某种原因，我多次输出一些路径（重复，三倍，甚至 4 次）。我只希望它为每个目录和子目录输出一次。

我会很感激我能得到的任何指导。提前致谢。这是我的代码

ExportFolders

我稍微更新了我的代码并简化了它。这是新代码。

#Add the import and snapin in order to perform AD functions
Add-PSSnapin Quest.ActiveRoles.ADManagement -ea SilentlyContinue
Import-Module ActiveDirectory

#Clear Screen
CLS

Function ExportFolders 
{
   #================ Global Variables ================

   #Path to user profiles in Barrington
    $Dir = "\\myFileServer\somedir\blah"

   #Get all user folders
    $ParentDir = Get-ChildItem $Dir | Where-Object {$_.PSIsContainer -eq $True} | where {$_.GetFileSystemInfos().Count -eq 0 -or $_.GetFileSystemInfos().Count -gt 0}

   #Export file to our destination
    $ExportedFile = "c:\temp\dirFolders.csv"

   #Duration in Days+ the file hasn't triggered "LastAccessTime"
    $duration = 1
    $cutOffDate = (Get-Date).AddDays(-$duration)

   #Used to hold our information
    $results = @()
    $details = $null

   #=============== Done with Variables ===============

    ForEach ($SubDir in $ParentDir)
    {
        $FolderName = $SubDir.FullName
        $FolderInfo = $(Get-Item $FolderName -force) | Select-Object FullName, LastAccessTime #| ft -HideTableHeaders
        $FolderLeafs = gci -Recurse $FolderName -force -directory | Where-Object {$_.PSIsContainer -eq $True} | where {$_.GetFileSystemInfos().Count -eq 0 -or $_.GetFileSystemInfos().Count -gt 0} | Select-Object FullName, LastAccessTime #| ft -HideTableHeaders

        $details = @{ "LastAccessTime" = $FolderInfo.LastAccessTime; "Folder Path" = $FolderInfo.FullName}
        $results += New-Object PSObject -Property $details

        ForEach ($FolderLeaf in $FolderLeafs.fullname)
        {
            $details = @{ "LastAccessTime" = $(Get-Item $FolderLeaf -force).LastAccessTime; "Folder Path" = $FolderLeaf}
            $results += New-Object PSObject -Property $details
        }

        $results
    }
}

ExportFolders

FolderInfo 变量有时会打印出多次，但 FolderLeaf 变量会打印出一次。问题是，如果我从打印出 folderInfo 的详细信息中移动或删除结果变量，则不会打印出父目录。仅显示所有子目录。还有一些目录是空的，不会打印出来，我希望打印出所有目录，包括空目录。

更新后的代码似乎可以很好地打印所有目录，但正如我提到的，我仍然得到一些重复的 $FolderInfo 变量。

我想我必须输入一个条件或其他东西来检查它是否已经被处理，但我不确定我会使用哪个条件来做到这一点，这样它就不会被打印多次。

在你的ExportFolders你Get-ChildItem -Recurse中，然后遍历所有调用Get-FolderItem. 然后在Get-FolderItem您为 Robocopy 提供/S标志中的标志，$params.AddRange(@("/L", "/S", "/NJH", "/BYTES", "/FP", "/NC", "/NFL", "/TS", "/XJ", "/R:0", "/W:0"))该/S标志表示复制子目录，但不是空的。所以你又在递归了。可能您只需要删除/S标志，以便您在ExportFolders.

回应编辑：

你$results在循环里面。因此，您将有第一个重复项，$subdir然后第二个重复 n-1 个，依此类推。

ForEach ($SubDir in $ParentDir) {
    #skipped code
    ForEach ($FolderLeaf in $FolderLeafs.fullname) {
         #skipped code
    }
    $results
}

应该

ForEach ($SubDir in $ParentDir) {
    #skipped code
    ForEach ($FolderLeaf in $FolderLeafs.fullname) {
         #skipped code
    }
}
$results
