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.

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 others think

Another case of trivial command added to another trivial command, resulting in a still trivial command.

Most of the people reading this site can use netstat, and it takes someone really *special* to not know grep, yet still be on this site.

And yet another netstat command finds its way onto the site. The search bar must be invisible.

Comment by atoponce 421 weeks and 4 days ago

I don't care if this command is trivial or just another netstat. The output format is useful for me, maybe useful for other users or for someone that collects different ways to use netstats. :-)

Comment by lfcipriani 421 weeks and 4 days ago

lfcipriani, the appropriate resource for you would be 'man netstat', then, not this site.
