title: Answer no to all questions using the yes command
body: <p>I'm trying to remove <strong>all</strong> files <em>except</em> read-only ones, but this command removes all of them anyway:</p>
  <pre class="lang-sh prettyprint-override"><code>yes n | rm *
  </code></pre>
  <p>Did I do something wrong? If not, why doesn't it work?</p>
