title: How do you pass arguments to custom zsh functions?
body: <p>How do you pass arguments to custom zsh functions?<br>
  For instance:</p>
  
  <pre class="lang-sh prettyprint-override"><code>function kill_port_proc(port) {
      lsof -i tcp:&lt;port interpolated here&gt;| grep LISTEN | awk '{print $2}'
  }
  </code></pre>
  
  <p>I'm seeing so many examples online with ZSH functions, but there barely anything on passing arguments and interpolating them.</p>
