Using the CLI Editing Features 1.3 Editing Features 1.3.1 Entering Commands A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command show interfaces status ethernet 8, show, interfaces and status are keywords, ethernet is an argument that specifies the interface type, and 8 specifies the port. To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter: Console(config)# username admin password smith When working with the CLI, the command options are not displayed. The command is not selected from a menu, but is manually entered. To see what commands are available in each mode or within an interface configuration, the CLI does provide a method of displaying the available commands, the command syntax requirements and in some instances parameters required to complete the command. The standard command to request help is ?. There are two instances where help information can be displayed: • Keyword lookup - The character ? is entered in place of a command. A list of all valid commands and corresponding help messages are is displayed. • Partial keyword lookup - If a command is incomplete and or the character ? is entered in place of a parameter. The matched keyword or parameters for this command are displayed. To assist in using the CLI, there is an assortment of editing features. The following features are described: • Terminal Command Buffer • Command Completion • Keyboard Shortcuts 1.3.1.1 Terminal Command Buffer Every time a command is entered in the CLI, it is recorded on an internally managed Command History buffer. Commands stored in the buffer are maintained on a First In First Out (FIFO) basis. These commands can be recalled, reviewed, modified, and reissued. This buffer is not preserved across device resets. Keyword Up-arrow key Ctrl+P Down-arrow key Description Recalls commands in the history buffer, beginning with the most recent command. Repeats the key sequence to recall successively older commands. Returns to more recent commands in the history buffer after recalling commands with the up-arrow key. Repeating the key sequence will recall successively more recent commands. By default, the history buffer system is enabled, but it can be disabled at any time. For information about the command syntax to enable or disable the history buffer, see history. There is a standard default number of commands that are stored in the buffer. The standard number of 10 commands can be increased to 216. By configuring 0, the effect is the same as disabling the history buffer system. For information about the command syntax for configuring the command history buffer, see history size. To display the history buffer, see show history. Page 14
