　　3.3.1 命令行在线帮助

　　通过上述各种在线帮助能够获取到帮助信息，分别描述如下：

　　(1) 在任一命令模式下，键入help获取有关帮助系统的简单描述。

　　Quidway> help

　　Help may be requested at any point in a command by entering

　　a question mark '?'. If nothing matches, the help list will

　　be empty and you must backup until entering a '?' shows the

　　available options.

　　Two styles of help are provided:

　　1. Full help is available when you are ready to enter a

　　command argument (e.g. 'show ?') and describes each possible

　　argument.

　　2. Partial help is provided when an abbreviated argument is entered

　　and you want to know what arguments match the input

　　(e.g. 'show use?').
