Executable Octave script: odd behavior when called with option ‘-display’

[Bernd Lütkenhöner]

Hi

Trying to call an executable Octave script with the option -display I found an odd behavior. This behavior can already be found in the trivial script ‘hello’:

#! /usr/bin/octave -qf
disp('Hello world');

Calling this script as

./hello
./hello -disp xyz
./hello -display

yields, as expected, the output ‘Hello world’. However, no output appears if I call the script as

./hello -display xyz

I could easily avoid the problem by changing, in my software, the name of the option (e.g. ‘disp’ instead of ‘display’). However, I am curious to understand what goes wrong.

My Octave version is 4.2.2 (running under Ubuntu).
