Here's a neat trick:
	cd /
	du -ks * | sort -nr |more
lists the directories in size order, with total
disk used in k. This lets you find the places
that are the disk hogs!

Another snippet that might help:
	cd foo
	find . -atime +60
finds files that havn't been accessed for 60 days or more.

and of course:
	cd foo
	find . \( -name core -o -name "*~" \)  -ok rm -f \{ \} \;
to nuke all core files, and all temporary files 
(name ends with ~) that haven't been accessed for 60 days.

And, you've checked /var/log/* for out-of-control log
files, yes?

Happy hunting...
