Saving History Commands
The CLI can automatically save the commands that have been used lately to the history buffer. You
can know the operations that have been executed successfully, invoke and repeatedly execute them
as needed. By default, the CLI can save up to ten commands for each user. You can use the
history-command max-size
command to set the capacity of the history commands buffer for the
current user interface (For the detailed description of the
history-command max-size
command, refer
to
Login Commands
in the
System Volume).
In addition:
z
The CLI saves the commands in the format that you have input, that is, if you input a command in
its incomplete form, the saved history command is also incomplete.
z
If you execute a command for multiple times successively, the CLI saves the earliest one.
However, if you execute the different forms of a command, the CLI saves each form of this
command. For example, if you execute the
display cu
command for multiple times successively,
the CLI saves only one history command; if you execute the
display cu
command and then the
display current-configuration
command, the CLI saves two history commands.
Follow these steps to access history commands:

Up-arrow key or
Ctrl+P
Displays the earlier history
command, if there is any.
Access the next history

Down-arrow key or
Ctrl+N

command, if there is any.
You may use arrow keys to access history commands in Windows 200X and XP Terminal or Telnet.
However, the up-arrow and down-arrow keys are invalid in Windows 9X HyperTerminal, because they
are defined in a different way. You can press
Ctrl+P
or
Ctrl+N
instead.
