title: Ruby require_relative
body: <p>This is incredibly hard to google for.  I have a file that is located in </p>
  
  <pre><code>/folder_1/folder_2/folder_3/my_ruby_file_to_be_executed.rb 
  </code></pre>
  
  <p>Inside that file I need to require this file </p>
  
  <pre><code>/folder_1/folder_4/file_to_require.rb
  </code></pre>
  
  <p>I cant workout how to write the relative path from one to the other.<br>
  I am using ruby 1.93</p>
