Script for combining multiple mods

[Amonchakad]

I'd really like to use this script to merge some mods,but I haven't got the slightiest clue on how to use it: I've never used perl,and I've tried downloading that perl program for windows,but it's a huge mess, so I went on another pc who has Ubuntu, and I tried your instructions for Linux, but it just says something like "no file found".
I'm a total newbie of Linux, so...does the combineMods file need to be in a particular directory? Do the mods need to be in the same one? Anything else that you might explain for this program to work?
