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

Know a better way?

If you can do better, submit your command here.

What others think

maybe we need sudo to perform that command..

My command and harpo's all need root privileges.

Comment by flatcap 215 weeks ago

for i in /var/spool/cron/*....doesn't work for me on SLES 11.

Comment by harpo 215 weeks ago

Hmm... Sorry. I don't have a copy of Suse handy to find out where they're hiding.

The Filesystem Hierarchy Standard says that's where cron jobs should live:

On SLES one has to type:

for i in /var/spool/cron/tabs/*;
