Accessing History Commands; Configuring The History Buffer Size - HP A5830 Series Configuration Manual

Accessing history commands

Use arrow keys to access history commands in Windows 200X and XP Terminal or Telnet.
In Windows 9X HyperTerminal, use Ctrl+P or Ctrl+N. They are defined differently and the up and down
arrow keys are invalid.
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 incomplete.
If the same command is executed repeatedly, the switch saves the earliest record. However, the same
command is executed in different formats. The system saves them as different commands. For example:
If display c is executed repeatedly, the system only saves 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 history-command max-size command. For more
information about the history-command max-size command, see Fundamentals Command Reference.
