htop
Interactive text-mode process viewer for Linux
htop is an interactive process viewer for Linux, similar to top but
with an improved and more user-friendly interface.
It allows scrolling the process list both vertically and horizontally,
killing processes without entering their PIDs, and provides
a visual representation of CPU, memory and swap usage.
Supports mouse interaction, customizable display, and tree view.
