HP Accessing history commands, Configuring the history buffer size

Accessing history commands

Follow a step below to access history commands:

To do…	Use the key/command…	Result
Display history commands	display history-command	Displays valid history commands you
		used
Display the previous history	Up arrow key or Ctrl+P	Displays the previous history command, if
command		any
Display the next history	Down arrow key or Ctrl+N	Displays the next history command, if any
command

NOTE:

You can use arrow keys to access history commands in Windows 200X and XP Terminal or Telnet. However, the up and down arrow keys are invalid in Windows 9X HyperTerminal, because they are defined differently. You can use Ctrl+P or Ctrl+N instead.

•The commands saved in the history command buffer are in the same format in which you typed the commands. If you type an incomplete command, the command saved in the history command buffer is also incomplete.

•If you execute the same command repeatedly, the switch saves only the earliest record. However, if you execute the same command in different formats, the system saves them as different commands. For example, if you execute the display cu command repeatedly, the system saves only one command in the history command buffer. If you execute the command in the format of display cu and display current-configuration respectively, the system saves them as two separate commands.

•By default, the CLI can save up to 10 commands for each user. To set the capacity of the history command buffer for the current user interface, use the history-command max-size command. (For more information about the history-command max-size command, see the chapter “Logging in to the switch commands.”

Configuring the history buffer size
