PowerShell - 将特定文件从源子文件夹移动到具有相同子文件夹结构的目标

Question

我正在使用PS脚本将5个最新文件按源文件类型从源目录移动到目标目录，同时保留子文件夹结构。例如，我想将任何以AB_开头的文件从ParentFolder1 \ FolderA，ParentFolder1 \ FolderB，ParentFolder1 \ FolderC等移动到ParentFolder2 \ FolderA，ParentFolder2 \ FolderB，ParentFolder2 \ FolderC。

ParentFolder1

--FolderA

---- AB_1234.txt

---- AB_5678.txt

---- XY_9876.txt

- --- XY_9876.txt

- 文件夹B

---- AB_1234.txt

---- AB_5678.txt

---- XY_9876.txt

---- XY_9876.txt

--FolderC

---- AB_1234.txt

---- AB_5678.txt

---- XY_9876.txt

---- XY_9876.txt

有没有一种方法，以配合成这样的循环？这是我到目前为止：

$source = "C:\Test" 
$dest = "E:\archive" 
$AB = Get-ChildItem -Path $source -include AB_* -Recurse | Where-Object {-not $_.PsIsContainer} 
$XY = Get-ChildItem -Path $source -include XY_* -Recurse | Where-Object {-not $_.PsIsContainer} 
$keep = 5 
$logfile = "E:\_archive\temp\log_{0:MM-dd-yyyy}.log" -f (Get-Date) 

if ($AB.Count -gt $keep) { 
    $AB | Sort -property LastWriteTime | Select-Object -First ($AB.Count - $keep) | Move-Item -destination $dest\AB -Force -Verbose 
    } 
Else 
    {"No AB_ files to archive." | Out-File $LogFile -Append -Force} 

if ($XY.Count -gt $keep) { 
    $XY | Sort -property LastWriteTime | Select-Object -First ($XY.Count - $keep) | Move-Item -destination $dest\XY -Force -Verbose 
    } 
Else 
    {"No XY_ files to archive." | Out-File $LogFile -Append -Force}

你可能会更好使用Robocopy。

function Move-Newest-Files 
{ 
    param (
     [parameter(Mandatory = $true)] [string] $source, 
     [parameter(Mandatory = $true)] [string] $destination, 
     [parameter(Mandatory = $true)] [array] $filter, 
     [parameter(Mandatory = $false)][int] $keep = 5 
    ) 

    try 
    { 
     $source = Resolve-Path $source 

     $list = Get-ChildItem -Path $source -Include $filter -Recurse -Force | 
      Where-Object { -not $_.psIsContainer } | 
      Sort-Object -property LastWriteTime -descending | 
      Select-Object -First $keep 

     foreach ($file in $list) 
     { 
      $destfile = $file -replace [regex]::Escape($source), $destination 
      $destpath = Split-Path $destfile -Parent 

      if (!(Test-Path $destpath)) 
       { $null = New-Item -ItemType Container -Path $destpath } 

      Move-Item $file -Force -Destination $destfile 
     } 
    } 

    catch 
    { 
     Write-Host "$($MyInvocation.InvocationName): $_" 
    } 
} 

Move-Newest-Files . "D:\xyzzy" @("*.cs", "*.txt", "*.exe") 10
