Command History

The CLI provides the command history function. You can use the display history-command command
to view a specific number of latest executed commands and execute them again in a convenient way.
By default, the CLI can store up to 10 latest executed commands for each user. You can view the
command history by performing the operations listed in

Table 1-3

.

This command displays the
command history.

Recall the previous history
command

Press the up arrow key or Ctrl+P

This operation recalls the previous
history command (if available).

Recall the next history command

Pressing the down arrow key or
Ctrl+N

This operation recalls the next
history command (if available).

z

Because the Windows 9x HyperTerminal explains the up and down arrow keys in a different way,
the two keys are invalid when you access history commands in a Windows 9x HyperTerminal
environment. However, you can use Ctrl+P and Ctrl+N instead to achieve the same purpose.

z

When you enter the same command multiple times consecutively, only one history command entry
is created by the command line interface.

Error Prompts

If a command passes the syntax check, it will be successfully executed; otherwise, an error message
will be displayed.
