Start by reading a good Ruby primer - 
http://www.ruby-doc.org/docs/ProgrammingRuby/ is browsable online for 
free, or there are many to choose from any buy. Type in and run the 
examples. Then start writing your own code, and when you get stuck at a 
particular point, you will be able to ask a more specific question.

For example: if you get stuck at iterating over all the files in a 
directory, look at Dir.glob, which is also callable as Dir[]

    Dir["foo.*"].each do |fn|
      puts fn
    end

Also, browse the archives of this list. An almost identical question to 
yours (about counting flight arrivals and departures) was asked a day or 
two ago.

Good luck,

Brian.
