Powershell：搜索子文件夹并在包含file1.txt的每个子文件夹上运行脚本并继续搜索

Question

我正在寻找一个脚本的帮助：

将在子文件夹中搜索，并且每次找到WIM文件时，都会使用wsus的最新更新进行更新。当该脚本完成后，它将继续下一个子文件夹。

这里有你到目前为止的代码：

$thismonth = (get-date).AddMonths(0).ToString("yyyMM")
$lastmonth = (get-date).AddMonths(-1).ToString("yyyMM")  
$2ndlastmonth = (get-date).AddMonths(-2).ToString("yyyMM")  
$date = get-date -f "yyyMM"
$LogName = "wim_update_$($thismonth).log"
$UpdatesPath = "d:\WSUS\WsusContent\*"
$MountPath = “d:\temp\mount”
$folder = Get-ChildItem -Path "D:\Distribution\Operating Systems"
########### DISM Mount path ########
Set-Location "d:\Distribution\Servicing\x86\"

forEach ($os in $folder)
{
    ###########Alias########
    $WimFile = “d:\Distribution\Operating Systems\$os\sources\install.wim"
    Write-Host $WimFile

    if (-Not (Test-Path ($Wimfile))) { continue }

    ########### Backup WIM File######## 
    Copy-Item "d:\Distribution\Operating Systems\$os\sources\install.wim" -Destination "d:\backup\install-$os-$thismonth.wim"
    if (-Not $?)
    {
        Write-Host "Failed to copy WIM file"
        continue
    }

    ./DISM /Mount-Wim /WimFile:$WimFile /index:1 /Mountdir:$MountPath
    if (-Not $?)
    {
        Write-Host "Failed to mount WIM file"
        continue
    }

    ############ Apply updates
    $UpdateArray = Get-Item $UpdatesPath | where{$_.extension -eq ".cab"}
    ForEach ($Updates in $UpdateArray)
    {
         ./DISM /image:$MountPath /LogPath:d:\Temp\$LogName /LogLevel:3 /Format:List /Add-Package /Packagepath:$Updates
         Start-Sleep –s 10
    }
    Write-Host "Updates Applied to WIM" -foregroundcolor red -backgroundcolor yellow

    ./DISM /Commit-Wim /Mountdir:$MountPath

    ########### DISM : Unmount WIM file ######## 
    ./DISM /Unmount-Wim /Mountdir:$MountPath /commit
    ./DISM /Cleanup-Wim
}


###########Remove N-2 ######## 
#Remove-Item "d:\backup\$os\install-$os-$2ndlastmonth.wim"
