I'm running octave 3.8 with the gui in Ubuntu 14.04. I have an infinite loop somewhere in my program and it seems like the terminal doesn't respond to the typical keypresses to stop execution. (eg. Ctrl+C, Ctrl+Z) When I run programs in the terminal, I can just press Ctrl+C, but that doesn't seem to work here. What can I do to halt execution?

    When you started the GUI for the first time on Octave 3.8, you should have gotten a warning that the GUI was experimental. You will notice that you need to use `--force-gui` too as well. You should try Octave 4.0, the first release with GUI as stable. – carandraug Oct 08 '15 at 11:44

    @carandraug I'm using octave v.4.0.0 GUI (ubuntu 16.04) and I see the same issue. I can't cancel a command running midway, not even with ctrl+c on the command window. Even though it looks like it's stopped, by CPUs are still working like crazy. – Felipe Feb 15 '17 at 03:29

    Same in 4.4.1 ... Ctrl+C answer below did work – KornMuffin Aug 26 '18 at 17:17

To stop a running command or script in octave GUI or prompt:

  1. Ctrl+C

you will see:

less -- (f)orward, (b)ack, (q)uit

To abort (and close the GUI or command line):

  1. Control+C

To just stop printing the output of the command or script (?):

  1. q
  2. Enter

It's a long-running bug that hasn't been fixed since 2012, run with --no-gui if possible.

after going through lots of bugs report and all.

Finally by hitting (ctr + c + Enter) at command window (below the pause statment) execution gets terminated.

hope it works for u too.
