title: Application file tracing on the runtime
body: <p>I'm working on a software that I must add some new features on it. Its on Linux and runs on the terminal. </p>
  
  <p>What I want to know is how can I find out all the files that being used when I run a certain command. </p>
  
  <p>Note that The application is so large has a lot of files for different daemons. I'm concerned about one daemon and I want to know what files from the app are responsible about running this daemon.
  Anyone have a clue about this ? 
  Thanks</p>
