如果输出流是标准输出，并且没有被重定向至文件或管道，则选定的页将出现在屏幕上。
If the output stream was stdout, and if it was not redirected to a file or a pipe, the selected pages will appear on the screen.
与标准输出流一样，可以对stderr进行重定向或使用管道进行传输，但是您需要告诉Shell您希望处理stderr而不是stdout。
Like the standard output stream, stderr can be redirected or piped, but you need to tell the shell that you want to deal with stderr instead of stdout.
而说出“Chocolate”或“Strawberry”会将调用流定向到缺省的、其他路径的连接对象——comingup上。
Saying "Chocolate" or "Strawberry" will direct the call flow to the default, else-path connection object, ComingUp.
