Start Yorick by typing its name to your terminal emulator. When you are done, use the quit function to exit gracefully:
% yorick Yorick ready. For help type 'help'. > quit % |
You can interrupt Yorick at any time by typing Control-C; this causes an immediate runtime error (see Errors). (Your terminal emulator and operating system must be able to send Yorick a SIGINT signal in order for this to work. On UNIX systems, you can set this character using the intr option of the stty command; Control-C is the usual setting.)
