Announcement: Parallel Disk Usage (pdu) — A highly parallelized, blazing fast disk usage visualizer

Here is the link to the git repository in case you desire none of my ramblings: https://github.com/KSXGitHub/parallel-disk-usage.

About dust

In the past few months, I have always used dust to visualize disk usages of heavy directories. It displays an intuitive bottom-up tree from heavier items to lighter ones. Every item is attached with a percentage bar that allow me to compare the relative size 2 sibling items as well as their parent. I quite like it.

I would soon discover its limits however.
