title: Creating a timed launchd plist
body: <p>I'm trying to create a plist for the LaunchAgents folder that will run perpetually and call a shell script every 30 seconds. It started with a template that <a href="http://arunxjacob.wordpress.com/2008/08/28/mac-launchd-and-launchctl-the-osx-alternative-to-cron/" rel="nofollow noreferrer">I got here</a> and that I tried to tailor to fit my needs, but it's still not working. Any help?</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt;
  &lt;plist version="1.0"&gt;
  &lt;dict&gt;
      &lt;key&gt;Label&lt;/key&gt;
      &lt;string&gt;com.Intel_Watchdog&lt;/string&gt;
      &lt;key&gt;ProgramArguments&lt;/key&gt;
      &lt;array&gt;
          &lt;string&gt;/Library/A_Intel_WATCHDOG/A_WatchDog.sh&lt;/string&gt;
      &lt;/array&gt;
      &lt;key&gt;StandardErrorPath&lt;/key&gt;
      &lt;string&gt;/dev/null&lt;/string&gt;
      &lt;key&gt;StandardOutPath&lt;/key&gt;
      &lt;string&gt;/dev/null&lt;/string&gt;
      &lt;key&gt;StartInterval&lt;/key&gt;
      &lt;integer&gt;30&lt;/integer&gt;
      &lt;key&gt;RunAtLoad&lt;/key&gt;
      &lt;true/&gt;
  &lt;/dict&gt;
  &lt;/plist&gt;
  </code></pre>
  
  <p>Thanks so much!</p>
