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

du and sort to find the biggest directories in defined filesystem

I had the problem that our monitoring showed that the "/" filesystem is >90% full. This command helped me to find out fast which subdirs are the biggest. The system has many NFS-mounts therefore the -x.

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives
for i in G M K; do du -hx /var/ | grep [0-9]$i | sort -nr -k 1; done | less

This command give a human readable result without messing up the sorting.

Know a better way?

If you can do better, submit your command here.

What others think

I like to add the -h flag; at least for me this makes it more readable. The command requires root permissions, so it's necessary to either run it as root or use sudo

I should have added that using the -h command messes up the sorting! apologies. I'm sure that it's possible to pipe the output through another formatting command could produce "human readable" file sizes and avoid the -h flag...
