How to list out Group Members of AD Groups using PowerShell Script

Step (1) Create a variable of the groups that you want to list

$group1 = “Administrators”,”Domain Controllers”,”Enterprise Read-only Domain Controllers”

Step(2) Create a path that you want to output

$csv = “C:\Users\User\Desktop\Folder\”+”Exported Groups_”+$group1+”.csv”

Step(3)Create foreach loop

$rtn = forEach($group in $group1)
{}

Step(4)Use Get-ADGroup, Get-ADGroup Member to get the required information

Get-ADGroup -Identity $group
Get-ADGroupMember -Recursive | select name

Step(5) Use pipeline to I/O process and use Out-File to create a file in $csv

| Out-File -FilePath $csv -Append

Step(6) whole powershell script

$group1 = "Administrators","Domain Controllers","Enterprise Read-only Domain Controllers"
$csv = “C:\Users\User\Desktop\Folder\”+”Exported Groups_”+$group1+”.csv”
$rtn = forEach($group in $group1)
{
Get-ADGroup -Identity $group |  Get-ADGroupMember -Recursive | select name | Out-File -FilePath $csv -Append
Add-Content -Value "The aboves are $group" -Path $csv
}
