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.

Download

Zig version (stable)

2.2.1 (ncdu-2.2.1.tar.gz - changes - requires Zig 0.9.0 or 0.9.1)

See the beta release announcement for information about the motivation for the rewrite and some of the differences with the C version.

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.

Linux users/distros may want to apply this patch to Zig to fix a possible crash.

Convenient static binaries for Linux: i486 , x86_64 , ARM and AArch64 . Download, extract and run; no compilation or installation necessary.

For users on Zig 0.10.0: see #213.

C version (LTS)

1.18 (ncdu-1.18.tar.gz - changes)

Lags a bit behind on the 2.x version in terms of features and performance, but is still being maintained and perfectly usable.

Development version The most recent code is available on a git repository and can be cloned with git clone git://g.blicky.net/ncdu.git/. The repository is also available for online browsing (and through cgit if you prefer that). The ‘master’ branch represents the C version, the Zig version can be found in the ‘zig’ branch. License
