That String creation is superfluous since the reference will be
overwritten anyway. You can instead do
falo = File.open(filename) { |f| f.read }
> File.open(filename) { |f| falo = f.read }
> words = falo.split('\n')
words actually holds lines.
The whole code can be condensed to
words = File.readlines(filename).each(&:chomp!)
or
words = File.foreach(filename).map(&:chomp)
