title: Update $PATH variable permanently
body: <p>Apologies if this duplicate but a lot of other threads are years old.</p>
  
  <p>I want to update my $PATH variable permanently so it doesn't reset everytime I quit Terminal. I have seen people suggest to run the following:</p>
  
  <pre><code>gedit ~/.bashrc
  </code></pre>
  
  <p>But this returns:</p>
  
  <pre><code>-bash: gedit: command not found
  </code></pre>
  
  <p>I have used Spotlight to search my hard disk for the <code>.bashrc</code> file and can't find it. Can anyone help?</p>
  
  <p>Thanks in advance...</p>
