config account message and the options listed below.
Figure 2–3 Example Command Parameter Help
In this case, the command config account was entered with the parameter <username>. The CLI will then
prompt to enter the <username> with the message, command: config account. Every command in the
CLI has this feature, and complex commands have several layers of parameter prompting.
In addition, after typing any given command plus one space, users can see all of the next possible sub-
commands, in sequential order, by pressing the ? key.
To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous
command appears at the command prompt.
