title: How to Debug application in linux
body: <p>Recently I was at some interview for Linux SYS Admin position and I've got the question "How do you debug some application in Linux".</p>
  
  <p>I am not new in Linux word and I actually stuck with this question.</p>
  
  <p>I am aware about "top", "ps" command, but may be there are some other advanced commands.</p>
  
  <p>I suggest that there is no one specific answer, but I think there is a couple of ways to do it.</p>
  
  <p>Can any one provide some way 'How to debug some application'?.</p>
  
  <p>Many thanks.</p>
