Something like this?

Code:

ls -l /proc/*/fd | cut -d' ' -f12- | grep -v 'null\|socket\|inode\|pipe\|proc\|/dev/\|/run\|^$\|net:' | xargs du -h | sort

no lsof?
that's bad.
maybe try

Code:

du

?

Can you go at it this way?

Code:

cd /
sudo du -sh *|less

Ignore results from /proc. You're at the base of the tree there. Go after the Gigs, and the Megs will look after themselves. /tmp can bulge massively, and most (but usually not all) of it can go. cd into the large ones, and repeat the second line above in /var, for instance. If you've a server online, you'll probably want to backup /var/log, before deleting space.

Something is probably spawning huge numbers of files and not deleting them, or you haven't been keeping house very well. This command

Code:

df -h

tells you what's actually free. Don't forget root's ~/.cache dir if root does much online. I presume /home is not on the / partition; if it is, move it's if possible to another partition and mount it on /home.
