title: Explaining the 'find -mtime' command
body: <p>I'm trying to remove all the dateed logs except the most recent. Before I execute a script to remove the files, I want to of course test my commands to make sure I'm bringing up accurate results.</p>
  
  <p>When executing these commands the date is:</p>
  
  <pre><code>Sep  1 00:53:44 AST 2014
  </code></pre>
  
  <p>Directory Listing:</p>
  
  <pre><code>Aug 27 23:59 testfile.2014-08-27.log
  Aug 28 23:59 testfile.2014-08-28.log
  Aug 29 23:59 testfile.2014-08-29.log
  Aug 30 23:59 testfile.2014-08-30.log
  Aug 31 23:59 testfile.2014-08-31.log
  Sep  1 00:29 testfile.log
  </code></pre>
  
  <p>I thought -mtime +1 was supposed to list all files over a day old. Why isn't the 8-30.log one listed?</p>
  
  <pre><code>find . -type f -mtime +1 -name "testfile*log"
  ./testfile.2014-08-27.log
  ./testfile.2014-08-28.log
  ./testfile.2014-08-29.log
  </code></pre>
  
  <p>This is the desired effect, but it was just trial and error. What is this 0 saying?</p>
  
  <pre><code>find . -type f -mtime +0 -name "testfile*log"
  ./testfile.2014-08-30.log
  ./testfile.2014-08-27.log
  ./testfile.2014-08-28.log
  ./testfile.2014-08-29.log
  </code></pre>
