Powershell AD: counting groups in office - powershell

Question

I am having issues in my thought process. I want an output of something like
'Group Name' 'Title' 'Count' and I am able to get the 'Group Name' and 'Title' Columns but I'm not sure how to count, say, all of the repeat groups in the 'sales' title. Where my code is right now, is searching the entire column to see if it finds that group name, and if it finds that column and then it move the counter by 1 (this is wrong because it my find a group name with a different title)
Any help would be greatly appreciated! Thank you
$allOffices = get-aduser -filter * -Properties physicaldeliveryofficename | Select-Object -ExpandProperty physicaldeliveryofficename #Selecting all offices
$uniOffices = $allOffices | Select-Object -Unique
$groups = $null
$global:ErrorActionPreference = 'silentlycontinue'
$finallist = #()
$count = 0
foreach ($office in $uniOffices) { # Loop through all unique offices
$peopleInOffice = $null
$peopleInOffice = get-aduser -filter * -properties office | Where-Object office -eq $office | Select-Object -ExpandProperty SamAccountName # Array of people in a certain office, selects username
foreach ($person in $peopleInOffice){
$groups = get-ADPrincipalGroupMembership $person
foreach($group in $groups) {
if(($finallist.'Group Name'-contains $group.name) -and ($finallist.'Title' -contains $office)){$count++}
$finallist+= $group| Select-Object #{N='Group Name';E={$group.name}},#{N='Title';E={($office)}},#{N='Count';E={$count}}
}
}
}
$finallist

So I started working on your problem, and I'm unsure what you're asking. Here's a greatly simplified and more efficient representation of your code:
$offices = Get-ADUser -Filter 'PhysicalDeliveryOfficeName -like "*"' -Properties PhysicalDeliveryOfficeName |
Select-Object -ExpandProperty PhysicalDeliveryOfficeName -Unique
$list = foreach ($office in $offices)
{
foreach ($person in (Get-ADUser -Filter "Office -eq '$office'" -Properties Office, MemberOf))
{
$person.MemberOf |
Get-ADGroup -Properties Name |
Select-Object -Property #(
#{
N = 'Group Name'
E = {$PSItem.Name}
}
#{
N = 'Title'
E = {$office}
}
)
}
}
At the end, you have a $list object which is an array of pscustomobject objects that you can manipulate. You can use Group-Object to determine how many groups there are with similar names using calculated properties, etc.
Using your problem statement:
how to count all of the repeat groups in the sales title
$list | Group-Object -Property Title | Select-Object -ExpandProperty Count
