title: How to identify which Daemon Process is writing to the file
body: <p>I need to identify a daemon process that is writing to a log file periodically. The problem is that I dont have any idea which process is doing the job, and I need to show some progress to the client by tomorrow. Anybody has any clue?</p>
  
  <p>I have already sorted out the daemon processes running in the system with the help of the PPID. Any help would be appreciated.</p>
  
  <p>Also I think it is possible (rarely) for a daemon not to have a PPID as 1. How can we find it out then?</p>
