title: How do I suppress shell script error messages?
body: <p>In my shell script I got these lines:</p>
  <pre class="lang-sh prettyprint-override"><code>rm tempfl.txt
  rm tempfl2.txt
  </code></pre>
  <p>If these do not exist I get the error messages:</p>
  <pre class="lang-sh prettyprint-override"><code>rm: tempfl2.txt: No such file or directory
  rm: tempfl.txt: No such file or directory
  </code></pre>
  <p>Is there a way to only suppress these messages even though they do not always appear, as the files might exist?</p>
