Fastfetch is a command that allows users to quickly display information about their operating system, software, and hardware. It is a lightweight utility that provides a concise summary of the system’s specifications. Users can customize the structure, load a custom configuration file, set a logo, and change the color of the keys and title.

Use case 1: Display system information

Code:

fastfetch

Motivation: This use case is helpful when you want to quickly view the specifications of your system, including the operating system, software, and hardware details. It allows you to get a snapshot of your system’s configuration without having to navigate through multiple settings and menus.

Explanation: By running the command ‘fastfetch’ without any arguments, the utility outputs the system information in a concise and easy-to-read format. It provides details such as the operating system name and version, desktop environment, CPU, memory, and GPU information.
