title: Codeigniter command line: The configuration file does not exist
body: <p>I have a Codeigniter 3.1.7 project locally and the same on my server for environnement testing.</p>
  
  <p>In local I can launch commands via:</p>
  
  <pre><code>php index.php manage save_existing_documents
  </code></pre>
  
  <p>and it works!
  But on testing, codeigniter work fine, 
  except with the command line^^
  He shows me:</p>
  
  <pre><code>The configuration file does not exist
  </code></pre>
  
  <p>Yet the config.php file is in application/config/testing/config.php^^</p>
  
  <p>The folder testing is a symlinks and it works for the rest of the project</p>
  
  <p>Thank for your help!</p>
