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

This command summarizes the disk usage across the files and folders in a given directory, including hidden files and folders beginning with ".", but excluding the directories "." and ".."

It produces a sorted list with the largest files and folders at the bottom of the list

du -h -d 1 | ack '\d+\.?\d+G' | sort -hr
find . -type d -print0 | xargs -0 du -s | sort -n | tail -10 | cut -f2 | xargs -I{} du -sh {} | sort -rn

This can give you an idea of the nature and extent of an issue on a failing hard drive.
