[olug] Unix Tip: GET YOUR IP-ADDRESS

[Blaufuss, Shane]

It's useful in scripts or programs, especially if you have a DHCP address
and want to dynamically start up IPCHAINS or such.  I use a line almost
exactly like the one below for that purpose.   I can drop a firewall script
on any of my machines and not need to manually edit it at all.
