Are you sure you have that correct. Your example below will give an error.

        octave:1> script.m
        script.m
        error: `script' undefined near line 8 column 1

Octave will interpret "script" to be a structure and "m" to be a field on that 
structure.

To run your script from a shell, you can add an option to allow octave to go 
interactive after running your script.

        $ octave --persist script.m

Or you can add "pause()" to the script. The plot window will then stay open 
until after you hit <return>
