Ok. Something is wrong with symbolic link. Please delete it and create it again.

        sudo rm /usr/local/bin/octave
        
        sudo ln -s /Applications/Octave.app/Contents/Resources/bin/octave 
/usr/local/bin/octave

What you should not see is ...

        $ ls -l /usr/local/bin/octave
        lrwxr-xr-x  1 root  wheel  54 Mar 20 16:38 /usr/local/bin/octave -> 
/Applications/Octave.app/Contents/Resources/bin/octave
