title: Montitor directory for new files
body: <p>I have a set of directories, named <code>00</code> trough <code>50</code>. Each of them contains a logfile.txt, which gets rotated once it hits 10Mb (~each week) to a logfile.old. The old logfile.old will be removed.</p>
  
  <p>I want to make copies of the logfiles, so I would like to make a script that monitors this directories and each time a new logfile.old appears, I want to copy this. I can't change anything in the <code>00</code> trough <code>50</code> directories or install anything as root.</p>
  
  <p>What's the nicest way to do this under linux (bash)?</p>
