NCurses Disk Usage
Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don’t have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

Note that the Zig language and compiler are still very much unstable. This version of ncdu will only work with the version of the Zig compiler noted above. Use the ncdu 1.x branch if this does not work for you or if you need a more stable compilation environment.
