title: grepping text string returns no result
body: <p>I have to find a lot of information in the esxi host for configuration.  </p>
  
  <p>When I run commands like:</p>
  
  <pre><code># grep -i "^Banner" /etc/ssh/sshd_config
  </code></pre>
  
  <p>I get no results but if I execute:</p>
  
  <pre><code>cat /etc/ssh/sshd_config
  </code></pre>
  
  <p>I can see in file the string "Banner /etc/issue".  </p>
  
  <p>Why does grep not return the information requested?  What am I missing?</p>
