ncdu (NCurses Disk Usage) is a disk utility for Unix systems. Its name refers to its similar purpose to the du utility, but ncdu uses a text-based user interface under the [n]curses programming library. Users can navigate the list using the arrow keys and delete files that are taking up too much space by pressing the 'd' key. It provides a swift and efficient way to view directories that are taking up disk space, and was primarily meant for remote shells. It runs on UNIX-based systems, such as Linux, BSD, and POSIX.

ncdu (NCurses Disk Usage) is a disk utility for Unix systems. Its name refers to its similar purpose to the du utility, but ncdu uses a text-based user interface under the [n]curses programming library. Users can navigate the list using the arrow keys and delete files that are taking up too much space by pressing the 'd' key. It provides a swift and efficient way to view directories that are taking up disk space, and was primarily meant for remote shells. It runs on UNIX-based systems, such as Linux, BSD, and POSIX. Users can install ncdu by running a package manager command in their terminal emulator (i.e. for Debian-based systems, apt install ncdu). Version 1.09 and later can export the file listing in JSON format.
ncdu was developed by Yoran Heling to learn C and to serve as a disk usage analyzer on remote systems over ssh. Version 2.0 of the program brought a full rewrite in the Zig programming language.
