Questions tagged [htop]

htop is CLI-based command that gives information on processes and memory usage, similar to top.

htop Install htop is not a pre-installed application and we can get it easily in the Software Center (by clicking that link), or by running these commands:

sudo apt-get update
sudo apt-get install htop

htop provides information about running processes and their resource usage in a way that many of its users consider more accessible than top. Novices may be able to use htop more easily than top, and its ease of use make it attractive to a number of more experienced users as well.

In particular, htop lets you scroll up and down, and lets you kill processes without manually specifying their process ID numbers.

See man top and man htop for more information.
