title: Linux: How to find the list of daemon processes and zombie processes
body: <p>I tried checking on Google, but I couldn't find much information related to the actual question. </p>
  
  <p>How do I get a consolidated list of zombie processes and daemon processes?
  How do I do it on different operating systems. Linux? AIX? Windows?</p>
  
  <p>I am sure that, based on PID, we cannot identify the type of process. Running through a terminal might not help either.</p>
