[Discuss] disk space analysis tools

[Ian Stokes-Rees]

And a few more:

multi-platform GUI-based:
jDiskReport for a java-based disk analyzer.

I've also written my own tool for doing this (single Python script):
https://github.com/ijstokes/duscan

This had the advantage of being runnable from a cron job and the 
results were always available to me (incl clickable HTML and pie 
charts).  It has the disadvantage of (potentially) creating O(N) 
additional small files, one per directory, if you choose to persist the 
disk usage summaries.  A sqlite (or similar) version would be a nice 
improvement!  Anyway, it accumulated disk usage by user and group, and 
kept a list of big files.  These were (and are) things that are 
relevant to me with a multi-TB multi-user system.

And while we're on the topic, but for OS X:
Disk Inventory X for OS X
