PoshRSJob通過文件目錄循環

Question

我想通過一個目錄（按最小文件排序）循環，獲取路徑和文件名，然後將這些結果泵入一個utility.exe程序。

我試圖做到這一點的多線程與PoshRSJob，但我不甚至看到了應用程序在任務管理器中顯示出來，我得到一個錯誤「null鍵沒有在字面上的哈希不允許的。」對於每個存在的文件（如果50個文件在目錄中，那麼我得到50個錯誤）。我也無法測試節流是否奏效，因爲沒有任何實際運行。

Import-Module C:\PoshRSJob.psm1 
Function MultiThread($SourcePath,$DestinationPath,$CommandArg, $MaxThreads){ 
    if($CommandArg -eq "import") { 
     $fileExt = "txt" 
    }else{ 
     $fileExt = "ini" 
    } 
    $ScriptBlock = { 
     Param($outfile, $cmdType, $fileExtension) 
     [pscustomobject] @{ 
      #get the full path 
      $filepath = $_.fullname  
      #get file name (minus extension) 
      $filename = $_.basename 
      #build output directory 
      $destinationFile = "$($outfile)\$($filename).$($fileExtension)" 
      #command to run 
      $null = .\utility.exe $cmdType -source `"$filepath`" -target `"$destinationFile`" 
     } 
    } 
    #get the object of the passed source directory, and pipe it into start-rsjob 
    Get-ChildItem $SourcePath | Sort-Object length | Start-RSJob -ScriptBlock $ScriptBlock -ArgumentList $DestinationPath, $CommandArg, $fileExt -Throttle $MaxThreads 

    Wait-RSJob -ShowProgress | Receive-RSJob 
    Get-RSJob | Receive-RSJob 
} 
MultiThread "D:\input" "D:\output" "import" 3 

Answer 1

您的scriptblock正在創建一個對象，您將$null = .\utility.exe +++定義爲屬性。正如它所說的，$null（無）的值不能是一個屬性名稱..我建議只是運行線..

您也許還想更改Wait-RSJob -part。你不指定工作，所以它從不等待任何事情。嘗試：

嘗試改變腳本塊到：

Import-Module C:\PoshRSJob.psm1 
Function MultiThread($SourcePath,$DestinationPath,$CommandArg, $MaxThreads){ 
    if($CommandArg -eq "import") { 
     $fileExt = "txt" 
    }else{ 
     $fileExt = "ini" 
    } 

    $ScriptBlock = { 
     Param($outfile, $cmdType, $fileExtension) 
     #get the full path 
     $filepath = $_.fullname  
     #get file name (minus extension) 
     $filename = $_.basename 
     #build output directory 
     $destinationFile = "$($outfile)\$($filename).$($fileExtension)" 
     #command to run 
     $null = .\utility.exe $cmdType -source `"$filepath`" -target `"$destinationFile`" 
    } 

    #get the object of the passed source directory, and pipe it into start-rsjob 
    Get-ChildItem $SourcePath | Sort-Object length | Start-RSJob -ScriptBlock $ScriptBlock -ArgumentList $DestinationPath, $CommandArg, $fileExt -Throttle $MaxThreads 

    Get-RSJob | Wait-RSJob -ShowProgress | Receive-RSJob 
} 
MultiThread "D:\input" "D:\output" "import" 3
