Answer by HuHa for Directory Stats command line interface?

You can use KDirStat (or the new QDirStat) together with the perl script that comes along with either one to collect data on your server, then copy that file to your desktop machine and view it with KDirStat / QDirStat.

The script does not seem to be included with the KDE 4 port K4DirStat, but it can still read and write the same cache files.
