Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What is my public IP-address?

Very effective, use only DNS protocol. The @ part is optional if you already set opendns servers as default ns servers.

Curl is not installed by default on many common distros anymore. wget always is :)

wget -qO- ifconfig.me/ip
curl -s 'http://checkip.dyndns.org' | sed 's/.*Current IP Address: \([0-9\.]*\).*/\1/g'

Know a better way?

What others think

I Like

curl icanhazip.com

the most, its short and nothing else then my ips comes out

Just add the +short option to the dig command and you'll get only the IP :) I like the fact that this uses OpenDNS since it's proven itself to be quite reliable.
