I'm working on trying to remove all subdomains from urls.
Example, I have a list of url's that may look like this:
nfl.com
mlb.com
apple.com
football.blogspot.com
forums.somesite.com
facebook.com
twitter.com
I need to know how I can write a regular expression in perl so that I can print just the domain of the website (ex: blogspot.com, not football.blogspot.com). Any simple way to do this?
