1.1 Running Octave
==================

On most systems, Octave is started with the shell command ‘octave’.
This starts the graphical user interface.  The central window in the GUI
is the Octave command-line interface.  In this window Octave displays an
initial message and then a prompt indicating it is ready to accept
input.  If you have chosen the traditional command-line interface then
only the command prompt appears in the same window that was running a
shell.  In either case, you can immediately begin typing Octave
commands.

   If you get into trouble, you can usually interrupt Octave by typing
‘Control-C’ (written ‘C-c’ for short).  ‘C-c’ gets its name from the
fact that you type it by holding down <CTRL> and then pressing <c>.
Doing this will normally return you to Octave’s prompt.

   To exit Octave, type ‘quit’ or ‘exit’ at the Octave prompt.

   On systems that support job control, you can suspend Octave by
sending it a ‘SIGTSTP’ signal, usually by typing ‘C-z’.
