htop

htop is an interactive process viewer for Unix-like operating systems. It provides a real-time, color-coded display of running processes, CPU usage, memory consumption, and other system information, offering an enhanced alternative to the traditional 'top' command.

This open-source tool is primarily used by system administrators, developers, and power users for monitoring system performance, identifying resource-intensive processes, and managing tasks directly from the terminal. It's designed for those who require a more intuitive and feature-rich command-line interface for process management.
