title: What's the equivalent of "find -mmin" in HP-UX?
body: <p>I created a script to check XML file available in the
  folder for more than four hours. If the XML is not processed for more than four hours then I need to send a mail
  for that I used the below find command but the mmin+240 is not working. Is there is any option to used instead of mmin. Please help on this.</p>
  
  <pre><code> find $OFILEPO/*.xml  -mmin+240  -exec ls -ltr {} + | wc -l
  </code></pre>
  
  <p>when I execute the above find command with mmin got the below error. </p>
  
  <pre><code>         **find: bad option -mmin
            0
           $ uname -a
            HP-UX** 
  </code></pre>
  
  <p>I think mmin is AIX command. Please suggest for HP_UX
  Thanks in Advance</p>
