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.

Functions

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

Gives the same results as the command by putnamhill using nine less characters.

Know a better way?

If you can do better, submit your command here.

What others think

Very nice, the -s option on the second tr gets rid of some false blank counts.

I like TheMightyBuzzard's version, but it doesn't work if your uniq has no -i option.

Comment by putnamhill 319 weeks and 3 days ago

TMB's solution leaves some words in mixed case (singleton mostly) and I use them as keys in the down stream process. So it's simpler if every is actually lowercased so I don't have to keep ignoring case.
