Look into the File class.
Ruby:

contents = File::open("myfile.txt", "r").read

Ruby:

File.open("enter_file_name", "r+") do |file|
  file.puts("This goes in the file!")
  file.puts("This also goes to the file!")
  lines = file.read  # Enitre file added to lines

  lines.each_line do |l|
    puts l[7] + '  ' +  l[4] + '  ' # Print the 5th and 8th character of each line 
  end
end
