Trying to return a set of CSV files based on group members in Active Directory.  Unfortunately this command doesn't look at the groups within the group. ie. HW (Global Security) contains groups like Denver_HW, and Aurora_HW.  But the command I am using is not returning the nested groups' members.

I have about 200 groups to go through, and I am satisfied with the results from the following command:

get-qaduser -memberof  GroupName | select firstname, lastname, description, samaccountname, userprincipalname | export-csv c:\groupname.csv

Option 1.
I want to query AD for all groups, enumerate members in the group and export results to a file called c:\groupname.csv

From there I will manually cut and paste members from Aurora_HW and Denver_HW into the main HW csv. 

Option 2 (preferred)
Enumerate all members within the top level groups to include members of nested group and export those results to .csv

So if I enumerate HW, it will automatically get everyone from HW, Aurora_HW, and Denver_HW and export it to a file called HW.csv

Then if I enumerate SA it will automatically get everyone from SA, Aurora_SA, and Denver_SA and export it to a file called SA.csv

Okay - maybe this was a little vague?

I am trying this:

gc .\groups.txt | % {
$group = $_
get-qaduser -memberof $group | % {
export-csv -path "C:\scripts\usergroups\$group.csv"
 }
}
