htop is an interactive process viewer for Unix systems. It’s nice because it’s more “graphical” and easier to read than the default Linux process viewer
top. It shows a frequently updated list of the processes currently running, normally ordered by the amount of CPU usage. Unlike
htop provides a full list of processes running, instead of the top resource-consuming processes.
Htop uses color and gives visual information about processor, swap and memory status.
sudo apt-get install htop
Users often deploy
htop in cases where Unix
top does not provide enough information about the system’s processes.
htop is also popularly used interactively as a system monitor. Compared to
top, it provides a more convenient, visual, cursor-controlled interface for sending signals to processes.
htop is written in the C programming language using the ncurses library. Its name is derived from the original author’s first name, as a nod to
pinfo, an info-replacement program that does the same.
