dua

dua is a high-performance disk usage analyzer built in Rust that helps you quickly understand where your storage space is going. Unlike traditional tools, it leverages parallel processing by default to scan your entire filesystem at maximum speed, extracting relevant information faster than conventional alternatives.

The tool offers two modes of operation: a command-line interface for quick analysis and an interactive terminal UI for exploring directories and managing files. In interactive mode, you can browse your disk structure, identify space-consuming files and folders, and delete unwanted data with built-in safeguards to prevent accidental removal.

Key capabilities include:

• Parallel scanning that maximizes SSD performance for rapid analysis
• Interactive exploration with keyboard navigation and visual hierarchy
• Safe deletion with multi-stage confirmation to prevent accidents
• Cross-platform support including Linux, macOS, Windows, and BSD systems
• Lightweight installation via package managers, Cargo, or pre-built binaries
• Configurable behavior through optional TOML configuration files

Whether you need a quick disk report or an interactive session to reclaim storage, dua delivers results in seconds rather than minutes. The tool is particularly valuable for developers and system administrators who spend time in the terminal and want efficient disk management without leaving their shell.
