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. 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.
After connecting to Bessemer (see Establishing a SSH connection), start an interactive session with the
srun --pty bash -i command.
The latest version of ncdu (currently version 1.15.1) is made available with the command:

$ ncdu --help
