What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get involved!

You can sign-in using OpenID credentials, or register a traditional username and password.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.

Universal configuration monitoring and system of record for IT.

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?

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.


There are 3 alternatives - vote for the best!

curl ifconfig.me

Return IP information about your external ip address with JSON format

wget -qO- icanhazip.com

Functions: wget

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?

If you can do better, submit your command here.

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.
