title: How does the word count program count hidden files?
body: <p>After creating a few directories and hidden files and running the following commands</p>
  
  <pre><code>ls -al | wc -l 
  ls -a1 | wc -l 
  </code></pre>
  
  <p>I get a difference in the total returned by the word count program. The </p>
  
  <pre><code>ls -al | wc -l
  </code></pre>
  
  <p>command returns one more count. Why is this?</p>
