Suppose our project  DIR tree structure is as:

and We need to search one object API customobject__c in the project.
i.e How many files have the reference of this object.
So what the solution here how we can serach in minimum time.
 Sol: Through eclipse searching and then need to prepare a excel 
 Sol: Manul Searching or some other time taking solution.

But here is a solution with the help of that we can searching within 10seconds and can make a excel by max of 2min.

So what the solution is that.

  3.CD aura (go to First folder of Project)
  4.Run this command
