RAILS SHELL APPLICATION IN 10 STEPS !!!
1.- rails shell -d mysql
2.- cd shell
3.- Edit config/database.yml
4.- rake db:create
5.- ruby script\generate scaffold Command execute:string
6.- rake db:migrate
7.- Delete public/index.html
8.- Edit config/routes.rb
     map.resources :commands
     map.root :controller => "commands"

9.- Edit the app/controllers/commands_controller.rb and add the @command_result variable in the show method.   
  def show
    @command = Command.find(params[:id])
    @command_result = %x[#{@command.execute.to_s}]

This is where we retrieve the @command.execute previously saved and execute it in the Rails server.

10.- Update the app/views/commands/show.html.erb

<pre>
  <%=h @command_result %>
