Re: where is the prompt: 0,1,2?

[Paul Kienzle]

In the command line documentation:

        octave --help

it says:

        Usage: octave [options]
        ...
          --interactive, -i       Force interactive behavior.
        ...

so try

        octave > tmp
        a=rand(4)
        24355
        exit
        cat tmp

Can it do this? Yes. See the man page for isatty

        man isatty
