title: ssh tail output lines only with keyword
body: <p>I'm trying to tail a large file in an ssh command prompt, but I need to filter it so it only displays lines that contain a particular keyword in them.</p>
  
  <p>I'm using this command currently to tail.</p>
  
  <pre><code># tail /usr/local/apache/logs/access_log
  </code></pre>
  
  <p>If possible please let me know what I would add to this command to accomplish this.</p>
