+Command scripting
+=================
+
+VyOS supports executing configuration and operational commands non-interactively from shell scripts.
+
+To include VyOS-specific functions and aliases you need to ``source /opt/vyatta/etc/functions/script-template`` files at the top of your script.
+
+.. code-block:: sh
+
+  #!/bin/vbash
+  source /opt/vyatta/etc/functions/script-template
+
+  exit
+
+Run 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:
+
+.. code-block:: sh
+
+  #!/bin/vbash
+  source /opt/vyatta/etc/functions/script-template
+
+  configure
+
+  set protocols bgp 65536 neighbor 192.168.2.1 shutdown
+
+  commit
+
+  exit
+
+
+Run 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.
+
+.. code-block:: sh
+
+  #!/bin/vbash
+  source /opt/vyatta/etc/functions/script-template
+
+  run show interfaces
+
+  exit
