title: Adding a new entry to the PATH variable in ZSH
body: <p>I'm using zsh terminal, and I'm trying to add a new entry (<code>/home/david/pear/bin</code>) to the <code>PATH</code> variable. I don't see a reference to the <code>PATH</code> variable in my <code>~/.zshrc</code> file, but doing <code>echo $PATH</code> returns:</p>
  <pre><code>/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
  </code></pre>
  <p>So I know that the path variable is being set somewhere.  Where is the <code>PATH</code> variable set / modified for the zsh terminal?</p>
