Command scripting

From VyOS Wiki

VyOS supports executing configuration and operational commands non-interactively from shell scripts.

Overview

To include VyOS-specific functions and aliases you need to source /opt/vyatta/etc/functions/script-template files at the top of your script.

#!/bin/vbash
source /opt/vyatta/etc/functions/script-template


exit

Running configuration commands

Configuration commands are executed just like from a normal config session.

For example, if you want to disable a BGP peer on VRRP transition to backup:

#!/bin/vbash
source /opt/vyatta/etc/functions/script-template

configure

set protocols bgp 65530 neighbor 192.0.2.1 shutdown

commit

exit

All of set, delete, edit, top, up, commit should work.

Running operational commands

Unlike a normal configuration sessions, all operational commands must be prepended with "run", even if you haven't created a session with configure.

#!/bin/vbash
source /opt/vyatta/etc/functions/script-template

run show interfaces

exit
