Duc – inspect and visualize disk usage

Duc is a library and suite of tools for inspecting disk usage.

Duc maintains a database of accumulated sizes of directories of the file system, and allows you to query this database with some tools, or create fancy graphs showing you where your bytes are.

Duc comes with a command line tool called duc, which is used to create, maintain and query the disk usage database.

Duc comes with a number of user interfaces for querying the database: use Duc on the console with a command line or ncurses interface, on graphical desktops with an X or OpenGL GUI, or over the web using the CGI interface.

The software uses Tokyo Cabinet to manage its database.

Features include:

  • Built to scale to huge filesystems.
  • Fast in operation – disk usage is stored in an optimized database.
  • Various sub-commands for querying or exploring the index:
    • duc info shows a list of available directory trees in the database, and the time and date of the last scan.
    • duc ls lists all files and directories under the given path on the console.
    • duc ui runs a ncurses based console user interface for exploring the file system usage.
    • duc gui starts a graphical (X11) interface representing the file system in a sunburst graph.
  • Handles multiple path arguments.
  • DPI handing for graph font size.
