Get-ChildItem equivalent of DIR /X

Question

How do I show a directory listing in 8.3 notation in PowerShell?

Answer 1

You can use WMI:

Get-ChildItem | ForEach-Object{
    $class  = if($_.PSIsContainer) {"Win32_Directory"} else {"CIM_DataFile"}
    Get-WMIObject $class -Filter "Name = '$($_.FullName -replace '\\','\\')'" | Select-Object -ExpandProperty EightDotThreeFileName
}

Or the Scripting.FileSystemObject com object:

$fso = New-Object -ComObject Scripting.FileSystemObject

Get-ChildItem | ForEach-Object{

    if($_.PSIsContainer) 
    {
        $fso.GetFolder($_.FullName).ShortPath
    }
    else 
    {
        $fso.GetFile($_.FullName).ShortPath
    }    
}
