How to Manage Linux Processes With htop – Guide
htop is a Linux tool divided into three sections (CPU and memory usage information, average load uptime and process view) that allows real-time monitoring of processes.

Htop is an interactive system monitor, process viewer and process manager designed for Unix systems. Originally conceived as an alternative to the Unix program top, it offers virtually the same functionality as top, but offers much more flexibility in viewing system processes.
