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.

Latest version

1.13 (ncdu-1.13.tar.gzpgp-sha1-md5 - changes)

I also have convenient static binaries for Linux i486 and ARM. Download, extract and run; no compilation or installation necessary (uses musl).

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.

Ncdu is entirely written in C and available under a liberal MIT license.

Packages and ports

Ncdu has been packaged for quite a few systems, here's a list of the ones I am aware of:

AIX - Alpine Linux - ALT Linux - Arch Linux - CRUX - Cygwin - Debian - Fedora - FreeBSD - Frugalware - Gentoo - GNU Guix - IPCop - OpenBSD - Mac OS X (Fink - Homebrew - MacPorts) - Puppy Linux - Solaris - Slackware - Slax Linux - Ubuntu - Void Linux

Packages for RHEL and (open)SUSE can be found on the Open Build Service.

A port to z/OS is available here.
