title: ruby: Hello World exercise
body: <p>I know that my question is not a new one but I will be more specific hopefully to get a specific answer as well.</p>
  
  <p>I am using:</p>
  
  <ul>
  <li>Ubuntu 11.10 --> (First time in my life though a virtual machine on windows vista)</li>
  <li>Tried to install rvm and Ruby --> (Went successfully but honestly i don't know were they are :D)</li>
  <li>Passed through vim tutorial</li>
  <li>Tried the Hello_World exercise as follows:</li>
  </ul>
  
  <p>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</p>
  
  <pre><code>:! mkdir rubymonk
  cd rubymonk
  :e hello_world.rb
  -------------------------
  vim (insert mode)
  puts "Hello World"
  -------------------------
  :wq
  </code></pre>
  
  <p>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</p>
  
  <ul>
  <li>Back to the Terminal</li>
  <li>typing: ruby hello_world.rb</li>
  <li>Got the usual error (ruby: No such file or directory -- hello_world.rb (LoadError)</li>
  </ul>
  
  <p>Hopefully I can get an answer from you guys.</p>
