Powershell 脚本打印出相同路径的重复条目

Question

我的 objective 是编写一个 powershell 脚本，该脚本将递归检查文件服务器中是否有 "x"（插入天数）旧或更旧的目录。

我运行最初解决了一些问题，我想我已经解决了大部分问题。我运行遇到的问题之一是 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，并将信息导出到一个易于阅读的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、三重，甚至 4 次）。我只想为每个目录和子目录输出一次。

如果能得到任何指导，我将不胜感激。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 变量有时会打印多次，但据我所见，FolderLeaf 变量只打印一次。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。

我想我必须设置一个条件或其他东西来检查它是否已经被处理过，但我不确定我会用哪个条件来做那件事，这样它就不会打印多次.

Answer 1

在您的 ExportFolders 中您 Get-ChildItem -Recurse 然后遍历调用 Get-FolderItem 的所有子文件夹。然后在 Get-FolderItem 中为 Robocopy 提供 $params.AddRange(@("/L", "/S", "/NJH", "/BYTES", "/FP", "/NC", "/NFL", "/TS", "/XJ", "/R:0", "/W:0")) 中的 /S 标志 /S 标志表示 copy 子目录，但不是空目录。所以你又在递归了。可能您只需要删除 /S 标志，以便您在 ExportFolders.

中执行所有递归

回应编辑：

您的 $results 在循环内。因此，第一个 $subdir 有 n 个重复项，第二个有 n-1 个重复项，依此类推。

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

应该是

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