can I understand wich .emacs I'm using?

[Renato]

Hi,
very simple question (for the "expert")
I don't know, wich .emacs Im using. Is there  a ariable than I can ask?
For a prob (that Rustom know well...) I've uninstalled my emacss on 
Debian wheezy  (apt-get remove emacs*)
ad I've installed "brand new" emacs (apt-get install emacs)

So, I think I've to search about .emacs, in my home dir. but I don't 
find it.

So: where can I look for?

TIA

Renato
