du and sort to find the biggest directories in defined filesystem

du -x / | sort -rn | less
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.

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...
