title: combine grep with the watch and netstat command
body: <p>Red Hat Enterprise Linux Server release 5.4 (Tikanga)
  2.6.18-164.el5</p>
  <p>I am trying to use the watch command combined with the netstat to see the 2 programs using certain ports.</p>
  <p>However, with the command I using below doesn't work for both words:</p>
  <pre><code>watch -n1 &quot;netstat -upnlt | grep gateway\|MultiMedia&quot;
  </code></pre>
  <p>Is this the correct way to grep for both program names.</p>
  <p>If I use one its ok, but both together doesn't work.</p>
