Question

I cannot find it anywhere, tried adding –silence, –quiet etc, but still the script prints everything on stdout as if it was the interactive mode.

I am running octave script with:

octave script.m

Answer 1

If you’re on a Linux or Mac OS X machine, you could try to use the standard shell constructs to solve your problem:

octave script.m > /dev/null

will gobble everything on the standard output from your script.

If CPU is your concern, the code you have is either badly written and would benefit from a rewrite (by adding at least semicolons after each statement) or you could try a dirty workaround.

What I’d try in that case, is shadowing the display function by a function that takes a single argument and doesn’t do anything. If you place that function in your working directory, much output should already disappear. If that’s not the case, the code might be using fprintf to output to the console and you could try shadowing that function. But beware that fprintf is also commonly used to write to files and has a more complex syntax to overload properly.

It’s not the nicest thing to do, but it might yield faster results (and lots of troubles during debugging).
