3.7.1 Command Completion
The CLI supports both command abbreviation and command completion. If the
keystrokes entered are enough to match a valid command, the CLI displays the
remainder of the command syntax when the <Tab> key or spacebar is pressed.
When typing a command, the <Tab> key or spacebar invokes auto-completion. If the
keystrokes entered are sufficient to identify a specific command, auto-completion
completes the command. If the letters are not sufficient to identify a specific
command, pressing the <Tab> key or spacebar displays commands matching the
letters entered.
The command completion functionality works for both keywords and for optional
parameters that have already been configured. When using command completion for
optional parameters, the <Tab> key must be used.
For example, entering “i <Tab> returns the following user-configured interface
names:
*A:ALU-12>config>router# interface "i
"igmp_interface" "igmp_interface2" "isis_interface"
System commands are available in all CLI context levels.
