NCDu

Ncdu provides a text‑mode interface for exploring disk usage on POSIX‑like systems. It scans directories and presents a navigable list of sizes, allowing users to locate large files and folders without a graphical environment. The tool is intended for remote servers, headless machines, and regular desktops alike.

The program supports parallel scanning (e.g., `-t8` for eight threads) and a binary export format that can be compressed and handle directory trees exceeding available memory. Color output is optional and can be enabled with `--color=dark`. Ncdu is distributed as static binaries for Linux, as well as source packages in both C (LTS) and Zig (stable) versions, and it is licensed under MIT.

It is packaged for many operating systems, including Linux distributions, BSD variants, macOS, and Windows, and the development repository is publicly available. The software focuses on speed, simplicity, and ease of use while remaining compatible with a wide range of platforms.
