I want to type something in console that will open some location (on example home dir) in already opened nautilus window. Is it possible?
No, I'm afraid you're asking for the impossbile.
You'd need dbus or something for that. Or an in-built management in Nautilus. Sadly as far as I know there is nothing like that available. (It won't separate it like n1t3 (Nautilus1 window, tab 3)).
