Get members by group from a forest

Question

I have multiple domains in our forest and I'm trying to pull a list (csv) of all the members of groups with a PCSupport in the name.
I've been able to get the groups or members of the group in my specific domain but not the others.
One or the other and haven't been able to put it all together. This has gotten me the farthest along, I've got all the groups listed, but I don't know how to feed this into additional scripting to get the groups and members into a csv.
Thanks in advance for any help

Hi Tom,
For example I use this expression to get members from a group and works fine for the CSV.
Import-Module ActiveDirectory
Get-ADGroupMember -identity "<group>" | select name | Export-csv -path C:\output\members.csv -NoTypeInformation
I think the | Export-csv -path is what you are looking for
