neofetch

Neofetch is a command-line tool that displays a summary of your computer's system information — things like your operating system, CPU, RAM, kernel version, and uptime — alongside your operating system's logo rendered in ASCII art (text characters arranged to form an image). It is written as a Bash script, which means it runs in your terminal without needing any special runtime installed. The output is designed to look visually impressive, making it popular for sharing screenshots of your desktop setup online. You can customize what information is shown and how, either through command-line options or a configuration file. You can even swap the ASCII logo for a custom image or your desktop wallpaper. Neofetch supports nearly 150 different operating systems, from mainstream Linux distributions to obscure systems like Haiku and Minix. You would use it when you want to quickly show off your system setup or need a nicely formatted overview of your machine's specs. It is primarily a cosmetic and social tool rather than a diagnostic one.
