Summary
du, stands for disk usage, remains a popular tool to estimate file space usage. It’s part of coreutils, a package of GNU software containing implementations for many of the basic tools which are used on Unix-like operating systems.
There’s many projects that look to improve on these tools. duf is one of the best. It’s a polished alternative to du which offers better presentation of information. We can tailor output to exactly what’s needed. For example, we can show and hide specific tables, as well as specific filesystems. We can also show or hide specific columns.
Portions of duf’s code are copied and modified from gopsutil, a port of psutil. psutil is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network, sensors).

What’s the performance like?
Pretty good considering it’s written in Go
I like duf, it’s really pretty cool.
One thing that’s bad is the way it includes the reserved spaced that file systems use. There’s about 5% of the space allocated for root on a filesystem.
This means that duf’s output is inconsistent with df.
That’s true. But which one is right?
