fastfetch [options]

fastfetch is a fast, highly customizable system information tool written in C. It displays information about your operating system, software, and hardware in a visually appealing format with ASCII art logos.
The tool is designed as a faster alternative to neofetch, screenfetch, and similar system info tools. It's highly configurable through JSON config files and command-line options, supporting custom module orders, colors, and logos.
fastfetch detects and displays OS, kernel, DE/WM, terminal, shell, CPU, GPU, memory, disk, battery, and many other system properties. It supports multiple platforms including Linux, macOS, Windows, and FreeBSD.

fastfetch was created by Linus Dierheimer (LinusDierheimer) in 2021 as a faster alternative to neofetch. It was written in C for performance, addressing complaints about neofetch's bash implementation being slow. The project gained popularity rapidly due to its speed and extensive customization options.
