To run:

1. install cmdwatch:

pkg add https://pkg.freebsd.org/FreeBSD:12:amd64/latest/All/cmdwatch-0.2.0_2.txz

2. download the script:

fetch https://gist.githubusercontent.com/luckman212/0fdea1cbdc0a561d781a52c7d34fb60d/raw/ffd321ef196fb1c919dd66700acdd4acc02b3e63/dpinger_static_routes.php

3. then

cmdwatch --interval=2 'php -q dpinger_static_routes.php'

or, if you don't want to install cmdwatch, you can use a simple while loop

while : ; do clear; php -q dpinger_static_routes.php ; sleep 2 ; done
