Re: Break out of program in interpreter

[Jose Torre-Bueno <jtorrebueno@...>]

Yes that does work.  However

while true do os.execute('echo hello world') end

cannot be stopped with ^C.  The only way to end it is to kill the whole terminal session.

Is there something about calling os.execute that prevents it from seeing ^C?  Perhaps the ^C is being caught by the new shell that os.execute starts?
