EdgeRouter - Add Commands to EdgeOS

Overview

Readers will learn how to add custom commands to the EdgeOS command line interface.

NOTES & REQUIREMENTS:

Applicable to the latest EdgeOS firmware on all EdgeRouter models. Please see the Related Articles below for more information.

In this example, an Operational Mode command is added to the command line that resets the console session (clear screen).

CLI: Access the Command Line Interface. You can do this using the CLI button in the GUI or by using a program such as PuTTY.

When first running the reset command, a single option exists:

ubnt@edgerouter:~$ reset ?
Possible completions:
 openvpn Reset OpenVPN

1. Log in as the root user.

sudo su

2. Navigate to the /opt/vyatta/share/vyatta-op/templates/reset directory.

cd /opt/vyatta/share/vyatta-op/templates/reset

NOTE: Commands added to the reset sub-directory will add them to the reset ? command tree.

3. Create a new directory named console.

mkdir console

4. Navigate to the newly created console directory.

cd console

5. Create a new file named node.def in the console directory and add the following contents (note the empty line at the bottom).

cat > node.def
help: Reset the Console
run: /usr/bin/reset

6. Use CTRL+D to exit out and save the script.

7. Exit back to the EdgeOS command line.

exit

Verify the configuration by trying out the new command:

ubnt@edgerouter:~$ reset ?
Possible completions:
 console Reset the Console
 openvpn Reset OpenVPN 

ubnt@edgerouter:~$ reset console
