title: Temporary files being created by cron
body: <p>I've noticed that within my user's directory (<code>/home/user/</code>) there are a bunch of files like....</p>
  
  <pre><code>index.html.25
  index.html.17
  index.html.23
  index.html.5
  index.html.9
  index.html.1
  index.html.32
  index.html.4
  </code></pre>
  
  <p>And also other files that happen to be the name of my crons that run.  I've verified that these files have no contents in them.  Their file size is 0.</p>
  
  <p>My crons use <code>wget [url]</code></p>
  
  <p>The thing is, none of these crons use my index page (which is PHP, not html).</p>
  
  <p>Any thoughts on why this might be happening?</p>
