6. Command Line Interface
The Command Line Interface (CLI) offers a generic control interface to the router and can be used to
get/set configuration parameters, apply updates, restart services or perform other system tasks.
It will be started automatically in interactive mode when logging in as
admin
user or by running
cli
-i
. However, the same syntax can be used when calling it from the system shell. A list of available
commands can be displayed by running
cli -l
.
The CLI supports TAB completion, that is expanding entered words or fragments by hitting the TAB key
at any time. This applies to commands but also to some arguments and generally offers a convenient
way for working on the shell.
Please note that each CLI session will perform an automatic logout as soon as a certain time of inac-
tivity (10 minutes by default) has been reached. It can be turned off by the command
no-autologout
.
6.1. General Usage
When operating the CLI in interactive mode, each entered command will be executed by the
RETURN
key. You can use the
Left
and
Right
keys to move the current point between entered characters or
use the
Up
and
Down
keys to search the history of entered commands. Typing
exit
as well as pressing
CTRL-c
twice or
CTRL-d
on an empty command line will exit the CLI.
