#2 Re: Determine your public IP address quickly Posted by mnaumann (213.39.xx.xx) on Fri 16 Mar 2007 at 12:20 You're a quick commenter. Indeed, aliasing it is a nice idea. And I'm a perfectionist who dislikes leading spaces. So, here's an update based on your suggestion. alias my_ip='wget -qO - checkip.dyndns.org|cut -d":" -f2|cut -d"<" -f1|cut -d" " -f2' Based on timing tests, wget + cut is indeed much faster than perl's GET + sed (as one would expect). wget + cut should also use less memory and CPU resources.
