Which w3wp.exe process belongs to which App Pool in IIS6 (with powershell)

Question

to date, I use this tool to tell which w3wp belongs to which App Pool

c:\windows\system32\cscript iisapp.vbs

How can I extract the same information with Powershell? Or maybe, with more informative results.

Thanks :)

This is by no means the only approach, but here is one I use. This is for PS v1, some code can be optimized for V2.

function get-apppools{
    [regex]$pattern="-ap ""(.+)"""
    gwmi win32_process -filter 'name="w3wp.exe"' | % {
        $name=$_.name
        $cmd = $pattern.Match($_.commandline).Groups[1].Value
        $procid = $_.ProcessId
        New-Object psobject | Add-Member -MemberType noteproperty -PassThru Name $name |
            Add-Member -MemberType noteproperty -PassThru AppPoolID $cmd |
            Add-Member -MemberType noteproperty -PassThru PID $procid 
    }
}

This outputs:

PS C:\Documents and Settings\jpogran> get-apppools

The iisapp script shows this:
