Multiple output formats including JSON export and database storage
Flexible sorting and display options such as apparent size, relative size, and item counts
Safety features like optional deletion prevention and read-only modes
Archive browsing for zip, jar, and tar files

The tool excels at helping system administrators and power users quickly locate storage bottlenecks, manage disk space efficiently, and automate analysis through command-line options. Whether you need an interactive exploration session or automated reporting, gdu adapts to your workflow with comprehensive configuration options and both interactive and non-interactive modes.
