多个广告组的总用户总数

Question

I've been trying to get the total number of users in several active directory groups and so far I've gotten this put together:

$Groups = Get-Content -Path $someFile
foreach ($Group in $Groups) {
    (Get-ADGroup $Group -Properties *).Member.Count
}

Of course, this spits out a number for each individual group, but I haven't come across any way of having ps add these numbers up and display the final total instead.

Answer 1

I don't have access to an AD server to test this, but this should work by assigning the member count to a variable and adding the total of the current group to the variable, then output the total count when complete.

$Groups = Get-Content -Path
Foreach ($Group in $Groups) {
    $totalusers += (Get-ADGroup $Group -Properties *).member.count
}
$totalusers

Answer 2

To get the count of unique members you could do something like this:

$script:cnt = 0
$Groups |
    Get-ADGroupMember |
    Select-Object -Expand DistinguishedName -Unique |
    ForEach-Object { $script:cnt++ }

If you want to resolve group members recursively (ie the members of nested groups as well) add -Recursive to Get-ADGroupMember .
