Using The Command History Function; Controlling The Cli Output - HP 10500 Series Configuration Manual

Using the command history function

The system automatically saves commands successfully executed by a login user to two command history
buffers:
• Command history buffer for the user line.
Command history buffer for all user lines.

The system follows these rules when buffering commands:
Buffering a command in the exact format in which the command was entered. For example, if you
•
enter an incomplete command, the buffered command is also incomplete. If you enter a command
with a command keyword alias, the buffered command also uses the alias.
If you enter a command in the same format multiple times in succession, the system buffers the
•
command only once. If you enter a command in different formats multiple times, the system buffers
each command format. For example, display cu and display current-configuration are buffered as
two entries but successive repetitions of display cu create only one entry.
• To buffer a new command when a buffer is full, the system deletes the oldest command entry in the
buffer.

Controlling the CLI output

This section describes the CLI output control features that help you identify the desired output.

command in the buffer and press Enter to
execute the command again.
•
In Windows 9x HyperTerminal, use Ctrl+P
and Ctrl+N to do so.
Use the history-command max-size
size-value command in user line view to set
