Here is a sample of how to use compare-object, just replace the string with a
call to a function that does the desired operation.
compare-object (gc list1.txt) (gc list2.txt) |
%{
if ($_.SideIndicator -eq "<=") {"$($_.InputObject) exists in file 1"}
if ($_.SideIndicator -eq "=>") {"$($_.InputObject) exists in file 2"}
}
