User & Group Manager (Bash + Whiptail GUI)

The User & Group Manager is a Linux system administration tool developed using Bash scripting and the Whiptail utility. It provides a simple, menu-driven graphical interface (via the terminal) that allows system administrators to manage users and groups efficiently without manually typing terminal commands. The project is designed to streamline common administrative tasks and improve usability through a text-based GUI.

Objectives

Simplify user and group management on Linux systems.

Provide a user-friendly interface for administrators using Whiptail.

Automate repetitive administrative tasks through scripted logic.

Functionality

The tool presents a menu interface through Whiptail. When a user selects an option, the selection is passed to a secondary Bash script that executes the required operation using a case statement. Upon completion, a status message is displayed, and the menu is presented again. The tool continues to loop until the user chooses to exit.
