Hello FreeBSD Geeks.
In this article I will show you how to find out your public IP address in FreeBSD Systems, with fetch:
$ fetch -q -o - http://www.ipchicken.com | grep -o -E '(^|[[:space:]])[0-9]*.[0-9]*.[0-9]*.[0-9]*([[:space:]]|$)'
I have used fetch, because wget is not installed by default on FreeBSD systems.
You can alias this oneliner:
$ alias get_ip='fetch -q -o - http://www.ipchicken.com | grep -o -E \'(^|[[:space:]])[0-9]*.[0-9]*.[0-9]*.[0-9]*([[:space:]]|$)\''
To make these alias persistent, do this:
$ echo 'alias get_ip=\'fetch -q -o - http://www.ipchicken.com | grep -o -E \'(^|[[:space:]])[0-9]*.[0-9]*.[0-9]*.[0-9]*([[:space:]]|$)\'\'' >> ~/.{bash,zsh,ksh,csh}rc
