This is good Topic here to share you.Some time some guy ask how i can watch our CPU processe. So Now day in market some software available,you just install in computer and run it. It saw you all information related CPU.

that is pretty helpful if you need the full process name otherwise top is the easiest.

Instead of that you can use lsof command which will show you list of files that particular process is accessing so you can trace a user.
