Get-Content “D:\Support\source\machines.txt” | foreach {
write-host “Adding: $_”
$device_add = Get-CMDevice -Name $_
if ($device_add ) {
Add-CMDeviceCollectionDirectMembershipRule -CollectionName “My_Collection” -ResourceID (Get-CMDevice -Name $_).ResourceID }
else
{ write-host “$_ dont exist in SCCM”
}
}

Just have one query, once we are done with PowerShell script execution we will be getting the exact device number for collection.
I have observed that there is change (Increase/Decrease) in collection devices after few days, and it keep on increasing and decreasing.
As per my understanding as this collection is Static, the number should not change.

Cause the objects are not exist in your directory.

Damn, I didn’t even know, that they had this function! Thx a lot
