I have a user list that is that is 1000's of lines long and has a few columns. I have another list that is hundreds of lines long. They are in two separate files. They have some common information between them. I want to grab all of that information from the list that is 1000's of lines long with the hundreds of lines long list. What is the best way to do this? I need a quick fix for today and this may be a regular thing.
