Re: "which octaverc is automatically modified when I update Octave"

What do you do to "update Octave"?

I'll assume you mean "savepath"?

Your .octaverc should in your home directory. Since the 2.0 series the way your 
path information is stored has been changed. I recommend you ...

(1) Type "pathdef" to see what is in your path and make note of the local 
portion you want to keep.
(2) Type "restoredefaultpath"
(3) Type "addpath ("<the local portion you want>")
(4) Type :"savepath"
