Using the CLI 141
For information about the command syntax for configuring the command
history buffer, see the history-size command in the Line command mode
chapter of this guide.
Negating Commands
For many commands, the prefix keyword no is entered to cancel the effect of
a command or reset the configuration to the default value. All configuration
commands have this capability. This guide describes the negation effect for
all commands to which it applies.
Show Command
The show command executes in the User Executive (EXEC) and Privileged
Executive (EXEC) modes.
Command Completion
CLI can complete partially entered commands when the user presses the
<tab> or <space> key. If a command entered is not complete, is not valid,
or if some parameters of the command are not valid or missing, an error
message is displayed to assist in entering the correct command. By pressing
the <tab> key, an incomplete command is changed into a complete
command. If the characters already entered are not enough for the system to
identify a single matching command, the <?>key displays the available
commands matching the characters already entered.
Short Form Commands
The CLI supports the short forms of all commands. As long as it is possible to
recognize the entered command unambiguously, the CLI accepts the short
form of the command as if the user typed the full command.
Keyboard Shortcuts
The CLI has a range of keyboard shortcuts to assist in editing the CLI
commands. The help command, when used in the User EXEC and Privileged
EXEC modes, displays the keyboard short cuts.
The following table contains the CLI shortcuts displayed by the help
command.
