Hi, There's probably a far better way that someone with some more experience will suggest, but the first thing that came to mind is to write a little program/script that does the following:
- read all the files, into their own list of packages - combine the lists, filling a list of package names, sorted in alphabetical order and removing duplicates - iterate through the combined list, for each package check each of the four individual lists and if it is in there output it, otherwise leave a space That should achieve it in a fairly simple way, and can be done with any language.
