Meet btop, an aesthetically pleasing system resource monitor that displays processor, memory, disk, network and process usage and statistics. btop is a lighter, faster version of C++, and is a continuation of bashtop and bpytop.
Over the years, the options available for command-line system monitoring tools have grown considerably. There are top, htop, glances, nmon, ytop, gtop, vtop and atop to name a few.
In Linux administration, it is important to monitor system performance and hardware resource usage in real time. Especially for production server environments.

- (Enter) - Displays the details of the selected process.
- (Pg Up) (Pg Down) - Jumps 1 page in the list of processes.
- (Home) (End) - Jumps to the first or last page of the process list.
- (Left) (Right) - Selects the previous/next sequence.
- (b, n) - Selects the previous/next network device.
- (e) - Toggles the process tree view.
- (r) - Inverts the sort order in the process box.
