Attribute disk usage to a directory tree.

du

What is using space in this tree

du -sh * | sort -rh | head

Limit to one depth

du -h --max-depth=1 /var | sort -rh | head

Files large enough to matter

find /var -type f -size +500M -exec ls -lh {} +

Apparent size versus allocated size

du -sh --apparent-size .
du -sh .

The difference is sparse files. A file can report a huge apparent size while occupying little disk.
