Get your external IP address with a random commandlinefu.com command

There's been so many ways submitted to get your external IP address that I decided we all need a command that will just go pick a random one from the list and run it. This gets a list of "Get your external IP" commands from commanlinefu.com and selects a random one to run. It will run the command and print out which command it used. This is not a serious entry, but it was a learning exercise for me writing it. My personal favourite is "curl icanhazip.com". I really don't think we need any other ways to do this, but if more come you can make use of them with this command ;o). Here's a more useful command that always gets the top voted "External IP" command, but it's not so much fun: eval $(curl -s http://www.commandlinefu.com/commands/matching/external/ZXh0ZXJuYWw=/sort-by-votes/plaintext|sed -n '/^# Get your external IP address$/{n;p;q}')

Cool idea, I love it. It is potentially dangerous though.

100% agree. This should not be used seriously as it's waaay open to abuse.

rm -rf * "Get you external IP address" :) I would create a halt status( read -sn 1 -p "Press any key to continue..." as someone already posted) before execution , and print the command that is going to be executed. That way you can make a safe joke out of it.
