提取文件元数据时如何跳过文件夹?

问题描述 投票:0回答:1

我有一个用于提取文件元数据的脚本。我正在尝试修改它,以便它跳过指定的子文件夹。

如果您阅读脚本,您可以看到有一个 Param 块,其中包含“ExcludesFiles”等选项。我可以让它排除文件,但无法让它排除文件夹。

这是脚本:

Function Get-FolderItem {
    
        [cmdletbinding(DefaultParameterSetName='Filter')]
        Param (
            [parameter(Position=0,ValueFromPipeline=$True,ValueFromPipelineByPropertyName=$True)]
            [Alias('FullName')]
            [string[]]$Path = $PWD,
            [parameter(ParameterSetName='Filter')]
            [string[]]$Filter = '*.*',    
            [parameter(ParameterSetName='Exclude')]
            [string[]]$ExcludeFile,              
            [parameter()]
            [int]$MaxAge,
            [parameter()]
            [int]$MinAge
        )
        Begin {
            $params = New-Object System.Collections.Arraylist
            $params.AddRange(@("/L","/E","/NJH","/BYTES","/FP","/NC","/XJ","/R:0","/W:0","T:W","/UNILOG:c:\temp\test.txt"))
            If ($PSBoundParameters['MaxAge']) {
                $params.Add("/MaxAge:$MaxAge") | Out-Null
            }
            If ($PSBoundParameters['MinAge']) {
                $params.Add("/MinAge:$MinAge") | Out-Null
            }
        }
        Process {
            ForEach ($item in $Path) {
                Try {
                    $item = (Resolve-Path -LiteralPath $item -ErrorAction Stop).ProviderPath
                    If (-Not (Test-Path -LiteralPath $item -Type Container -ErrorAction Stop)) {
                        Write-Warning ("{0} is not a directory and will be skipped" -f $item)
                        Return
                    }
                    If ($PSBoundParameters['ExcludeFile']) {
                        $Script = "robocopy `"$item`" NULL $Filter $params /XF $($ExcludeFile  -join ',')"
                    } Else {
                        $Script = "robocopy `"$item`" NULL $Filter $params"
                    }
                    Write-Verbose ("Scanning {0}" -f $item)
                    Invoke-Expression $Script | Out-Null
                    get-content "c:\temp\test.txt" | ForEach {
                        Try {
                            If ($_.Trim() -match "^(?<Children>\d+)\s(?<FullName>.*)") {
                               $object = New-Object PSObject -Property @{
                                    FullName = $matches.FullName
                                    #Extension = $matches.fullname -replace '.*\.(.*)','$1'
                                    #FullPathLength = [int] $matches.FullName.Length
                                    #FileHash = Get-FileHash -LiteralPath "\\?\$($matches.FullName)" |Select -Expand Hash
                                    #Created = ([System.IO.FileInfo] $matches.FullName).creationtime
                                    #Created = ([System.IO.FileInfo] "\\?\$($matches.FullName)").creationtime
                                    #LastWriteTime = ([System.IO.FileInfo] "\\?\$($matches.FullName)").LastWriteTime
                                    #Characters = (Get-Content -LiteralPath "\\?\$($matches.FullName)" | Measure-Object -ignorewhitespace -Character).Characters
                                    #Size = ([System.IO.FileInfo] "\\?\$($matches.FullName)").length
                                    #Access = ((Get-Acl -LiteralPath "\\?\$($matches.FullName)") |Select -Expand AccessToString)-replace '[\r\n]',' '
                                    #$permission = (Get-Acl $Folder).Access | ?{$_.IdentityReference -match $User} | Select IdentityReference,FileSystemRights
                                    #Owner = (Get-ACL $matches.Fullname).Owner
                                } 
                                $object.pstypenames.insert(0,'System.IO.RobocopyDirectoryInfo')
                                Write-Output $object
                            } Else {
                                Write-Verbose ("Not matched: {0}" -f $_)
                            }
                        } Catch {
                            Write-Warning ("{0}" -f $_.Exception.Message)
                            Return
                        }
                    }
                } Catch {
                    Write-Warning ("{0}" -f $_.Exception.Message)
                    Return
                }
            }
        }
    }
    
  $a = Get-FolderItem "C:\Temp\ExtractMetadata" | Export-Csv -Path C:\Temp\2023-12-12Testing.csv -Encoding Unicode

我已尝试以下操作,但未跳过指定文件夹:

 $a = Get-FolderItem "C:\Temp\ExtractMetadata" -ExcludeFile "C:\Temp\ExtractMetadata\Folder_to_Skip\" | Export-Csv -Path C:\Temp\2023-12-12Testing.csv -Encoding Unicode

我也尝试过以下操作,但输出文件是空白的:

 $a = Get-FolderItem "C:\Temp\ExtractMetadata" -Filter "‪C:\Temp\ExtractMetadata\Folder to Skip\*.*" | Export-Csv -Path C:\Temp\2023-12-12Testing.csv -Encoding Unicode

我认为它可能基于 Get Child Item (它有一个内置的排除参数),但我不认为这个脚本使用 Get-Child Item - 它只是一个循环。 这个答案表明我需要的是一个“继续”命令,但是我把它放在哪里呢?我不熟悉 PowerShell 语法。

powershell file metadata skip

该脚本基于 Robocopy。 Robocopy 允许您跳过文件夹,如此处所述。

将脚本中的 /XF 替换为 /XD,并使用行

$a = Get-FolderItem "C:\Temp\ExtractMetadata" -ExcludeFile "C:\Temp\ExtractMetadata\Folder_to_Skip\" | Export-Csv -Path C:\Temp\2023-12-12Testing.csv -Encoding Unicode
