Basic Usage

Create an index for a directory (e.g., /home) and store it in $HOME/.duc.db: $ duc index /home Show available indexes: $ duc info List files and directories in the current or a specific path:

$ duc ls
$ duc ls /home/alvin/Downloads

Get help for a subcommand:

$ duc help ls

Visualization

Display a size‑based bar chart for a directory: $ duc ls -Fg /home/alvin The -F flag adds file‑type indicators, and -g draws a graphical bar for each entry. Omit the path to visualize the current directory. Use -R for a tree‑style view: $ duc ls -R /home/alvin Launch the ncurses UI: $ duc ui /home/alvin Launch the X11 graphical UI:

$ duc gui /home/alvin
