title: Linux : Disabling File cache for a process?
body: <p>Is there a way to disable file cache for a particular process ?</p>
  
  <p>I have two process running A and B. </p>
  
  <p>I want file opened by A to remain in cache. </p>
  
  <p>and 
  I don't want to enable file cache for B so It doesn't replace the file cached by process in the memory. </p>
  
  <p>Is there a way to disable file cache for a particular process?</p>
