It looks like Brian answered your question, but if you are interested in 
the more idiomatic "ruby" approach you can do something more like:

def cargar_tokens(txt_file_name)
  tokens = []
  File.open(txt_file_name) do |file|
    file.each_line(' ') { |palabra| tokens << $1 if palabra =~ /(.+)/ }
  end

  tokens
end

if ARGV.empty?
  puts "I need one argument: 1) name of the file"
else
  tokens = cargar_tokens(ARGV.first)
end

The nice rubyisms are what make it fun, to me at least!
