title: How to make kill <tab> show the processes that are shown by ps
body: <p>When I type <code>kill -9</code> , it will show me all the processes[zsh: do you wish to see all 119 possibilities (119 lines)?]. A lot of processes from <code>/System/Library/</code> which I don't care.</p>
  
  <p>If I just type <code>ps</code> directly in shell, it will just show several processes. For example:</p>
  
  <pre><code>  PID TTY           TIME CMD
   5872 ttys000    0:00.08 -zsh
   6011 ttys000    0:00.00 ./server
   6014 ttys001    0:00.07 -zsh
  </code></pre>
  
  <p>How can I make this auto-completion show the processes that are only shown by using <code>ps</code>?</p>
  
  <p>PS: I am using Mac OS</p>
