The reason for this is simply that the plot is shown but the script just ends 
and closes the plot (probably so fast that you did not see the window appear 
at all). Usually I add a pause statement at the end of the script (one has to 
press a key to stop octave, it does not close automatically).

For example

#!/usr/local/bin/octave -qi
plot(1:10)
pause
