powershell - 如何使用Powershell检查重复的多个文件？

Question

我要检查重复的文件。如果文件的条件是这样，则意味着重复。名称相同，但扩展名不同。

AAA18WWQ6BT602.PRO
AAA18WWQ6BT602.XML

我可以用我的脚本弄清楚这种情况。但是如果我有多个这样的.XML文件，我就会遇到问题

AAA18WWQ6BT602.PRO
AAA18WWQ6BT602.XML
AAA18WWQ6BT601.XML
AAA18WWQ6BT604.XML

在这种情况下，它将不会检测到 AAA18WWQ6BT602.PRO和 AAA18WWQ6BT602.XML文件重复。
任何人都可以帮助我。
谢谢

$duplicate = @()
    @(Get-ChildItem "$Flag_Path\*.xml") | ForEach-Object { $duplicate += $_.basename }

    if(Test-Path -Path "$Flag_Path\*$duplicate*" -Exclude *.xml)
    {
        Get-ChildItem -Path "$Flag_Path\*$duplicate*" -Include *.xml | Out-File $Flag_Path\Flag_Duplicate
        Write-Host "Flag duplicated, continue for Error_Monitoring" 
        pause
        Error_Monitoring
    }
    else{
    Write-Host "Flag does not duplicate, continue the process"
}

您的脚本未正确迭代。您需要进行迭代检查。 Test-Path逻辑对我来说很困惑。我试图保留尽可能多的代码。

此脚本检查是否有任何后缀重复的xml基本名文件名(不仅是pro):

$Flag_Path = "C:\dir_to_be_checked"
$xmlFilesArray = @()
$allFilesExceptXml = @() # all files excluding xml files

# Get all the xml files
Get-ChildItem -Path $Flag_Path -Include "*.xml" | ForEach-Object { $xmlFilesArray += $_.basename }
# Get all files from the directory the xml files
Get-ChildItem -Path $Flag_Path -Exclude "*.xml" | ForEach-Object { $allFilesExceptXml += $_.basename }

# Iterate over list of files names without suffix
ForEach ($xmlFile in $xmlFilesArray) { 
    ForEach ($fileToCheck in $allFilesExceptXml) {
        If ($xmlFile -eq $fileToCheck) {
            # logging the duplicate file (specifying utf8 or the output would be UTF-16)
            Write-Output "$Flag_Path\$xmlFile.xml" | Out-File -Append -Encoding utf8 $Flag_Path\Flag_Duplicate
            Write-Host "Flag duplicated, continue with duplicate search" 
            # pause
            Write-Host "Press any key to continue ..."
            $x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
            Error_Monitoring
        } Else {
            Write-Host "Flag is not duplicated.  Continue with the search."
        }
    }
}
