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.
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.
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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

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:
Here's an awk version.
This method will also convert mac line endings.

The first version printed:
tr: empty string2
The second version printed:
sed: -i may not be used with stdin
Maybe I misunderstood the orginal problem.
If you don't have netcat, you can use curl.
If BREs can be used, this sed version will also get the job done.
The +short option should make dig less chatty.
If you're on a system that doesn't have nl, you can use cat -n.
Tested on MacOS X
Hi glaudiston, you can save a few chars by leaving out cat and pipe and still enjoy the added flexibility.
This version uses host and no ruby.
Requires the date command. This also works with some other comics. Here's a bash script that displays daily Garfield, Id, and Andy Capp:
I wasn't sure how to display the image, so I thought I'd try xml for a different twist.
Not perl but shorter.
For the record: I didn't build this. Just shared what I found that worked. Apologies to the original author!
I decided I should fix the case where http://example.com is not matched for the next time I need this. So I read rfc1035 and formalized the host name regex.
If anyone finds any more holes, please comment.
