ncdu
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
gaphical 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.
