# duc
> A collection of tools for indexing, inspecting and visualizing disk usage.
> Duc maintains a database of accumulated sizes of directories in the file system, allowing to query this database, or creating fancy graphs to show where data is.
> More information: <https://duc.zevv.nl/>.
- Index the `/usr` directory, writing to the default database location `~/.duc.db`:
`duc index {{/usr}}`
- List all files and directories under `/usr/local`, showing relative file sizes in a [g]raph:
`duc ls --classify --graph {{/usr/local}}`
- List all files and directories under `/usr/local` using treeview recursively:
`duc ls --classify --graph --recursive {{/usr/local}}`
- Start the graphical interface to explore the file system using sunburst graphs:
`duc gui {{/usr}}`
- Run the ncurses console interface to explore the file system:
`duc ui {{/usr}}`
- Dump database info:
`duc info`
