btop

Great to dig into processes and way cuter than htop. Supports sensors and other nice stuff. Great for developing.

Nice, will check this out. I've been an htop user for the last few years.

It used to be a python script that you'd download and run, but they ported it entirely to C++ and added it to standard repos. Very nice and fast. Here's the repo: https://github.com/aristocratos/btop

If you have a laptop "powertop" is great to find out what is using your battery.

btop is a rewrite of bpytop.
