title: How to delete lines in log file older than 14 days?
body: <p>I have a log that looks like this:</p>
  
  <pre><code>2018-09-18 03:29:38 [info]: /up request - ip: 63.143.42.249
  2018-09-18 03:34:38 [info]: /up request - ip: 63.143.42.249 
  2018-09-18 03:39:38 [info]: /up request - ip: 63.143.42.249 
  </code></pre>
  
  <p>I'm trying to use bash or another scripting language to delete all lines older than 14 days. Anyone have suggestions on how to do this? I've looked at GNU awk, but the examples weren't the most easy to run and still be readable.</p>
