title: Checking from shell script if a directory contains files
body: <p>From a shell script, how do I check if a directory contains files?</p>
  
  <p>Something similar to this</p>
  
  <pre class="lang-sh prettyprint-override"><code>if [ -e /some/dir/* ]; then echo "huzzah"; fi;
  </code></pre>
  
  <p>but which works if the directory contains one or several files (the above one only works with exactly 0 or 1 files).</p>
