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.

Know a better way?

If you can do better, submit your command here.

What others think

well im not sure, but isnt the lifehacker-cmd better cause it doesnt uses the pipe, or is it just a matter of taste?

Comment by berot3 190 weeks ago

I think the lifehacker command is much better as it only uses one command and has no pipes or redirects.....

Great Command.....
