How does it work?

github.com

magento/magento2/blob/b3f5588/app/code/Magento/Cron/Console/Command/CronCommand.php#L54-L59


new InputOption(
    self::INPUT_KEY_GROUP,
    null,
    InputOption::VALUE_REQUIRED,
    'Run jobs only from specified group'
),

github.com

magento/magento2/blob/b3f5588/app/code/Magento/Cron/Console/Command/CronCommand.php#L83-L83


$params[self::INPUT_KEY_GROUP] = $input->getOption(self::INPUT_KEY_GROUP);
