CLI Tips and Shortcuts
Completing a Partial Command with the Tab Key
If you cannot remember a complete command name, or if you want to reduce the amount of typing you
have to perform, enter the first few letters of the command, then press the Tab key. If only one command
begins with that character string, the system completes the command for you. If the characters you
entered indicate more than one command, the system beeps to indicate that the text string is not unique.
In the following example, the CLI recognizes conf as a unique string in EXEC mode, and completes the
command when Tab is pressed:
RP/0/RP0/CPU0:router# conf<Tab>
RP/0/RP0/CPU0:router# configure
The CLI displays the full command name. You must then press Return to execute the command. This
feature allows you to modify or reject the suggested command.
Tip If your keyboard does not have a Tab key, press Ctrl-I instead.
Identifying Command Syntax Errors
If an incorrect command is entered, an error message is returned with the caret symbol (^) at the point
of the error. In the following example, the caret symbol (^) appears where the character was typed
incorrectly in the command:
RP/0/RP0/CPU0:router# configure termiMal
^
% Invalid input detected at ‘^’ marker.
Note The percent symbol (%) indicates the line where the error message occurred.
To display the correct command syntax, enter the “?” after the command:
RP/0/RP0/CPU0:router# configure ?
Using the no and default Forms of a Command
The following sections provide information on using the various forms of a command:
• Using the no Form of a Command, page 3-4
• Using the default Form of a Command, page 3-5
Using the no Form of a Command
Almost every configuration command has a no form. In general, use the no form to disable a function.
Use the command without the no keyword to reenable a disabled function, or to enable a function that
is disabled by default. For example, IP routing is enabled by default. To disable IP routing, use the no ip
routing command; to reenable IP routing, use the ip routing command.
