Disk Usage Analyzer

This tool analyzes directory sizes within a filesystem to help users understand how space is consumed. Conceptually it traverses a directory tree, aggregates file sizes, and reports totals per path, with optional depth limits and human-readable units. It supports common command-line patterns found in Ubuntu terminals, enabling quick audits without heavy UI. The tool exposes inputs for target path, depth, and block size to tailor granularity, and outputs a structured summary of total usage, top directories, and per-directory breakdown. Benefits include faster capacity planning, targeted cleanup, and reproducible reports for system maintenance. Core differentiators are its CLI-oriented ergonomics, precise accounting of sparse and hidden files, and the ability to export results for automation. Use cases span on-boarding new servers, troubleshooting full disks, and preparing space estimates for software deployments. The implementation emphasizes robust error handling and compatibility with standard Linux tooling, allowing seamless integration into scripts and cron jobs. It is suitable for system administrators, developers, and IT operations teams who manage Ubuntu-like environments and need predictable disk accounting across large trees.
