Duc is a collection of tools designed to index, inspect, and visualize disk usage on a computer or server. It provides a convenient way to gather information about the sizes of directories and files, enabling users to query this data and create visual representations to better understand how disk space is being utilized.
Here are the key features and aspects of Duc:
Disk usage indexing: Duc maintains a database that accumulates and stores the sizes of directories and files on the file system. This indexing process enables efficient querying and analysis of disk usage information without the need to repeatedly scan the entire file system.
- Querying capabilities: Duc allows users to perform queries on the indexed disk usage data. Users can retrieve information about the sizes of specific directories or files, identify the largest files or directories, or search for items based on certain criteria. These queries help users gain insights into the distribution of disk space usage and locate areas that may require attention.
- Visualization options: Duc provides tools for creating visually appealing and informative graphs that illustrate disk usage patterns. Users can generate various types of graphs, such as pie charts, bar graphs, or treemaps, to visualize how disk space is allocated across directories and files. These visual representations help users identify space-consuming areas at a glance and understand the overall disk usage distribution.
- Efficient storage and retrieval: Duc’s database stores accumulated directory sizes in a compact format, optimizing storage efficiency. This allows for faster querying and retrieval of disk usage information, even for large file systems with numerous directories and files.
- Command-line interface: Duc is primarily a command-line tool, providing a set of commands and options for interacting with the disk usage data and generating visualizations. This makes it suitable for both interactive usage and automation through scripts or scheduled tasks.
- Customizability: Duc offers various configuration options that allow users to customize the behavior and appearance of the generated reports and visualizations. Users can specify the depth of the directory tree to be included in the analysis, choose the color schemes for graphs, and define other parameters to suit their preferences and requirements.
Duc is a powerful tool for analyzing disk usage and gaining insights into how storage space is utilized. Its indexing capabilities, querying functionality, and visualization tools enable users to efficiently explore and understand disk usage patterns, making it easier to identify areas of high disk usage and optimize storage allocation.
Please note that Duc may have specific command-line options and behavior that can be explored through the tool’s documentation or by using the built-in help command (e.g., “duc –help”).
duc Command Examples
1. Index the /usr directory, writing to the default database location ~/.duc.db:
# duc index /usr
2. List all files and directories under /usr/local, showing relative file sizes in a [g]raph:
# duc ls -Fg /usr/local
3. List all files and directories under /usr/local using treeview recursively:
# duc ls -Fg -R /usr/local
4. Start the graphical interface to explore the file system using sunburst graphs:
# duc gui /usr
5. Run the ncurses console interface to explore the file system:
# duc ui /usr
6. Dump database info:
# duc info
