This repository contains a comprehensive hardware diagnostic and benchmarking tool implemented as a single bash script (hardware.sh). The tool collects detailed system information including OS, virtualization, motherboard, CPU, GPU, memory, and storage devices. It runs performance benchmarks using sysbench, fio, and Geekbench5 to evaluate hardware quality, presenting results in a formatted terminal interface with optional JSON output for further analysis. The script features robust dependency handling, automatic installation of missing tools, and cross-platform support for numerous Linux distributions. It demonstrates strong bash scripting practices with sophisticated progress bars, intelligent fallback mechanisms for network services, and modular design for gathering diverse system metrics.
