PowerShell - 複製多個文件

Question

我已經編寫了PowerShell腳本來將新文件複製到服務器上的共享文件夾。

我想知道是否有一種方法，當我得到子文件夾中的新文件列表後，我可以一起復制它們 - 除了使用for-each並一次複製一個 - 以便我可以添加進度條。

這樣的事情可能是一個起點

# define source and destination folders 
$source = 'C:\temp\music' 
$dest = 'C:\temp\new' 

# get all files in source (not empty directories) 
$files = Get-ChildItem $source -Recurse -File 

$index = 0 
$total = $files.Count 
$starttime = $lasttime = Get-Date 
$results = $files | % { 
    $index++ 
    $currtime = (Get-Date) - $starttime 
    $avg = $currtime.TotalSeconds/$index 
    $last = ((Get-Date) - $lasttime).TotalSeconds 
    $left = $total - $index 
    $WrPrgParam = @{ 
     Activity = (
      "Copying files $(Get-Date -f s)", 
      "Total: $($currtime -replace '\..*')", 
      "Avg: $('{0:N2}' -f $avg)", 
      "Last: $('{0:N2}' -f $last)", 
      "ETA: $('{0:N2}' -f ($avg * $left/60))", 
      "min ($([string](Get-Date).AddSeconds($avg*$left) -replace '^.* '))" 
     ) -join ' ' 
     Status = "$index of $total ($left left) [$('{0:N2}' -f ($index/$total * 100))%]" 
     CurrentOperation = "File: $_" 
     PercentComplete = ($index/$total)*100 
    } 
    Write-Progress @WrPrgParam 
    $lasttime = Get-Date 

    # build destination path for this file 
    $destdir = Join-Path $dest $($(Split-Path $_.fullname) -replace [regex]::Escape($source)) 

    # if it doesn't exist, create it 
    if (!(Test-Path $destdir)) { 
     $null = md $destdir 
    } 

    # if the file.txt already exists, rename it to file-1.txt and so on 
    $num = 1 
    $base = $_.basename 
    $ext = $_.extension 
    $newname = Join-Path $destdir "$base$ext" 
    while (Test-Path $newname) { 
     $newname = Join-Path $destdir "$base-$num$ext" 
     $num++ 
    } 

    # log the source and destination files to the $results variable 
    Write-Output $([pscustomobject]@{ 
     SourceFile = $_.fullname 
     DestFile = $newname 
    }) 

    # finally, copy the file to its new location 
    copy $_.fullname $newname 
} 

# export a list of source files 
$results | Export-Csv c:\temp\copylog.csv -NoTypeInformation 

注：將顯示文件總數的進步，無論大小。例如：你有2個文件，一個是1 MB，另一個是50 MB。當第一個文件被複制時，進度將是50％，因爲一半的文件被複制。如果你想要總字節數，我強烈建議試試這個函數。只是給它一個來源和目的地。給予單個文件或整個文件夾時，複製
