i do apolagise - had to put kids to bed .It's 10.50pm here in wilds of north wales uk.
Anyway thanks for your understanding. Now what i want to do is i have 2 email lists list 1 has around 1000 emails no 2 list has 500 emails. I need to make sure that no 1 list does not have emails that are in no2 list.So i am hoping to end up with a 3rd result list that = list1 emails minus matching emails found in list2. Hope this is abit clearer than mud. Now i did read that this can be done in terminal or at least i think they mean terminal.this is the link
