Find User

I have a file in my home directory and I want to know all the users who have tried to read the file from my directory and or access the particualr file.

Could someone helpme in this as to how I can proceed further?

Thanks.

I don't know any standard UNIX tool to do that. So unless you have some kind of auditing daemon running that monitors file system activity there's little chance to get that information.

How can I know what is the file strcuture in my system ?

What do you mean by file structure?

File system? Directory tree?
