history
Project history and usage
duc is a disk-usage indexer and visualizer built for large Unix filesystems. Its niche is the middle ground between simple du-style scans and heavier monitoring systems: it indexes once, stores accumulated directory sizes, then lets users inspect the database through CLI, ncurses, X/OpenGL, or CGI views.
Project history
The project documentation presents duc as a collection of tools for indexing, inspecting, and visualizing disk usage. Its homepage emphasizes scale, saying it has been tested on filesystems with hundreds of millions of files and petabytes of storage.
The public GitHub release history shows a 1.0 release candidate in 2015 followed by 1.x releases, which matches its role as a mature small Unix utility rather than a fast-moving platform.
Adoption history
duc entered conventional Unix packaging channels: its homepage documents Debian and derivative installation, and the package metadata here shows availability across Homebrew, Debian, Fedora, Nix, Ubuntu, Alpine, and openSUSE-family packaging.
Adoption is mostly sysadmin and storage-operator oriented. It is useful where repeated recursive du scans are too expensive and where visual inspection is more useful than a single sorted list.
How it is used
The typical workflow is to run duc index over a filesystem subtree, then use commands such as duc ls, text UI, GUI, or web views to inspect where space is going. Its default database workflow makes it valuable on machines where disk usage analysis is repeated.
Because it keeps a database of accumulated sizes, duc is better suited to repeated exploration of large trees than one-shot disk usage commands.
Why package nerds care
duc is package-nerd-interesting as a classic small C/Unix utility: one executable name, man-page style documentation, broad distro packaging, and a stable purpose that has not accreted a large platform around itself.
It also represents a family of disk-usage tools that compete by data structure and UI rather than by cloud integration: ncdu, dust, gdu, and duc all solve the same operator itch with different tradeoffs.
Timeline
- 2015: duc 1.0 release candidate appears in the GitHub release history.
- 2015: duc 1.1, 1.2, and 1.3 releases follow.
- 2016: duc 1.4 release line begins.
- 2017: duc 1.4.3 is published in the GitHub release history.
Related projects
- duc is related in usage to ncdu, gdu, dust, and graphical disk usage viewers, but its distinguishing feature is the persistent indexed database used by several front ends.
- It also belongs to the same operational toolbox as du, df, find, and filesystem inventory scripts used by Unix administrators.
