Do you mean, how to read it into a Hash? Just read the file one line at 
a time, splitting it into key and value as you desire, and then add that 
as a new element into the Hash.

Methods you may find useful:

File.open
each_line   (for an IO object, yields a string for each line)
chomp       (for a String object, chop off the final newline)
split       (for a String object, split by default on spaces)

Hash methods:

h = {}          # create an empty Hash
h = Hash.new    # an alternative way of doing the same thing
h[key] = value  # create or overwrite an entry in the Hash
