fastfetch

Fastfetch is a command‑line utility that gathers a wide range of system information and presents it in a formatted, visually oriented output. It retrieves details such as operating system version, kernel, hardware specifications, desktop environment, and other runtime data, arranging them in a concise layout that can be customized through configuration files. The tool is implemented primarily in C, emphasizing speed and low resource usage while allowing users to adjust the displayed fields and styling.

The program targets developers, system administrators, and power users who need a quick snapshot of a machine’s configuration across many platforms. It supports Linux, macOS, Windows 8.1 and newer, Android, FreeBSD, OpenBSD, NetBSD, DragonFly, Haiku, and SunOS derivatives, with active testing on x86‑64 and aarch64 architectures. Users can invoke it directly from a terminal, and the output can be piped or incorporated into scripts for automated reporting.

Installation is handled through the package managers of numerous Linux distributions, as well as manual installation from pre‑built binaries or source. Fastfetch’s configuration system includes example presets, and its documentation provides screenshots for various operating systems, helping users tailor the appearance to their preferences.
