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.

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

A Quick variation to the latest commands list with the new-lines skipped. This is faster to read.

What others think

Doesn't work for me. Is this gawk-dependent?

Comment by porges 409 weeks and 3 days ago

works for me however i would like to be able to print to a file without bash throwing a fit

awk: line 1: syntax error at or near ,

It is gawk dependent. Replace "awk" with "gawk" and it should work.

Comment by DEinspanjer 406 weeks and 5 days ago

I like this but I think the description is misleading. The correct description I believe is:

list the descriptions of the latest commands posted to CLFU.
