4. After an incomplete command keyword is entered, if the suffix of this keyword is unique, press the Tab key to display
the complete keyword.
For example
Ruijie# show conf<Tab>
Ruijie# show configuration
5. In any command mode, run the help command to obtain brief description about the help system.
For example
Ruijie(config)#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 pr?'.)
1.3.4 Abbreviated Commands
If a command is long, you can enter a part of the command that is sufficient to identify the command keyword.
For example, to run the interface gigabitEthernet 0/1 command in GigabitEthernet 0/1 interface configuration mode, enter
the abbreviated command as follows:
Ruijie(config)#int g0/1
Ruijie(config-if-GigabitEthernet 0/1)#
1.3.5 No and Default Options of Commands
Most commands have the no option. Generally, the no option is used to disable a feature or function, or perform the
operation opposite to the command. For example, run the no shutdown command to perform the operation opposite to the
shutdown command, that is, enabling the interface. The keyword without the no option is used to enable a disabled feature
or a feature that is disabled by default.
