thank you for the clarification.. now i have some x bitcoins in the bitcoin core (installed in linux machine). How should i protect it? Should i encash it or leave it just like that?
If you move the Bitcoins out of your wallet, you will not get any BCC. You have to have your Bitcoin
in your wallet at the moment of fork (for cloning).
So I would
not move them out.
I'll give another example. You want to make a copy of a file.
You type in linux
copy file1 file2 (or something like that).
If you don't have file1, the copy will fail.
If you do have file1, you'll end up with both files.
If, after copy, you edit one of them, it will
not affect the other one.
if i leave it just like that, will those coins remain n my wallet or missed? How do i get bcc in additional?
If you leave them alone, your Bitcoin will remain as they are. Your wallet will still show the x Bitcoin.
If you'll want to access your BCC, you'll have to do some more advanced operations (export your private keys from Bitcoin Core, download BCC client, import the private keys into that new client); if the fork will happen, you better come and ask then. Before the fork the BCC doesn't exist so people will not be able to give you detailed steps.
