Asks you if you are sure. If you are not, it will return an error code. Is useful in scripts where you want a confirmation before executing.
For example if you have a destructive script in package.json (when using
&& the next command wont be run if current command exits with an error code):
$ npm run cleanAre you sure? [y/n]...
Can be invoked with your own question and allowed answer:
$ sure --question "Type ok to continue." --yes "ok"Type ok to continue....
