Using command history

The CLI automatically saves the commands recently used in the history command buffer. Access and execute
them again.

Accessing history commands

Task
Display history commands.
Display the previous history
command.
Display the next history command.
NOTE:
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.
Use Ctrl+P or Ctrl+N instead.
The commands saved in the history command buffer are in the same format in which you entered the
•
commands. If you enter an incomplete command, the command saved in the history command buffer
is also an incomplete one.
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 run display cu 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 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 history-command max-size. (For more information
about history-command max-size, see "Logging in to the switch commands."
