ncdu as an alternative to du (analyzing file and directory sizes)

Ncdu is an interactive console (ncurses) disk usage analyzer. A fast alternative to the du command! Monitor and navigate directories.

ncdu df du linux

ncdu is a really nice little program using the ncurses library, which calculates the size of files and directories, i.e. exactly like the good old du command.

ncdu linux
Unlike the du command, it's somewhat interactive, letting you walk through directories (like Midnight Commander) and monitor them on an ongoing basis.
