powershell - 计算Active Directory用户

Question

下面的代码应该用于对用户进行计数和比较，并输出总计数，但是不知何故结果为空。我需要做什么来修复它？

$groups = $A_group, $B_Group
$gm     = @()

foreach ($group in $groups) {
    $gm += Get-ADGroupMember $group -Recursive |
           `where {$_.objectclass -eq 'user'} |`  
           ' select SamAccountName'
}

($gm.samaccountname | Select -Unique).Count
Write-Output total: ($gm.samaccountname | Select -Unique).Count

Answer 1

您可以通过更像Powershell的方式来执行此操作。

$groups  = $A_group, $B_Group
$uniqueMemberCount = $groups |
    Get-ADGroupMember -Recursive |
    Where-Object {$_.objectClass -ieq "user"} |
    Select-Object -Unique |
    Measure-Object |
    Select-Object -ExpandProperty Count

Write-Output "Total: $uniqueMemberCount"
