title: See what process last touched a file
body: <p>On a linux box that there is some process regularly changing permissions on directories and files, roughly daily. This is not a process that I set up and I have no idea what it is.</p>
  
  <p>I have root access and I can easily change permissions manually to get access back but it is a bit annoying.</p>
  
  <p>Is there an way to see a list of processes that have last touched a file? Or alternatively how would I go about logging process activity on the file. </p>
