PowerShell script to return members of multiple security groups

This is cleaner and will put in a csv.

Import-Module ActiveDirectory

$Groups = (Get-AdGroup -filter * | Where {$_.name -like "**"} | select name -expandproperty name)


$Table = @()

$Record = [ordered]@{
"Group Name" = ""
"Name" = ""
"Username" = ""
}



Foreach ($Group in $Groups)
{

$Arrayofmembers = Get-ADGroupMember -identity $Group | select name,samaccountname

foreach ($Member in $Arrayofmembers)
{
$Record."Group Name" = $Group
$Record."Name" = $Member.name
$Record."UserName" = $Member.samaccountname
$objRecord = New-Object PSObject -property $Record
$Table += $objrecord

}

}

$Table | export-csv "C:\temp\SecurityGroups.csv" -NoTypeInformation

If you don't care what groups the users were in, and just want a big ol' list of users - this does the job:

$Groups = Get-ADGroup -Filter {Name -like "AB*"}

$rtn = @(); ForEach ($Group in $Groups) {
    $rtn += (Get-ADGroupMember -Identity "$($Group.Name)" -Recursive)
}

Then the results:

$rtn | ft -autosize
