PowerTUI

shutd is a modern C++ command-line utility designed for Linux systems (tested on Arch Linux) that wraps the native shutdown and reboot commands with a clear, interactive countdown interface.

Instead of running a silent system command, shutd provides real-time visual feedback through a clean terminal UI, helping users clearly see how much time remains before the system powers off or reboots.
