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

find /path/to/files -type f -mtime +7 ! -name '*gz' | xargs -r gzip

The grep is not needed. "-r" for xargs does not create an error message if no file is found.

find /search/path/ -type f ! -iname *.gz -mtime +7 -exec gzip

You could make this command quicker by not piping
