How do I add another column to a System.Object using a list in Powershell? - object

Question

I am making a script to query active directory via powershell and pull all computers that contain a username in the description field, then filter that list with only computers last logged in the past 14 days.
This is what I have so far:
$queryAD = Get-ADComputer -SearchBase 'OU=West Division,DC=cable,DC=comcast,DC=com' -Properties Name, Description -Filter {(Name -like "WA*") -and (Description -like $wildCard)} | Select-Object Name, Description
$lastLogon = $queryAD | Select-Object -ExpandProperty Description | %{$_.replace(("$NTname" + ";"),"").split(";")[0]} | %{get-date $_ -format d}
I'd like to add the list generated from $lastLogon to $queryAD, right now $queryAD is returning two columns with headers Name and Description. I need a third header added called Last Logon Date and contain the list in $lastLogon. Please advise.

You could assign the values to an array of objects to make your output cleaner (if this method is providing you the data you want) like so:
$queryAD = Get-ADComputer -SearchBase 'OU=West Division,DC=cable,DC=comcast,DC=com' -Properties Name, Description -Filter {(Name -like "WA*") -and (Description -like $wildCard)} | Select-Object Name, Description
$computer_list = #()
foreach($computer in $queryAD) {
$computer_info = New-Object PSObject -Property #{
Name = $computer.Name
Description = $computer.Description
LastLogonDate = $computer | Select-Object -ExpandProperty Description | %{$_.replace(("$NTname" + ";"),"").split(";")[0]} | %{get-date $_ -format d}
}
$computer_list += $computer_info
}
in which case $computer_list will contain all of the info you're gathering in tidy objects.
...but this method seems overcomplicated. Look into this blog entry by Matt Vogt for a better way to query for old machines in AD.
