System monitoring dashboard for the terminal (with examples)
1: Show the system stats dashboard
gtop
Motivation
The motivation for using this command is to get a comprehensive overview of the system’s performance and resource usage. This allows users to monitor key metrics in real-time, such as CPU usage, memory usage, and disk activity. By using gtop, users can quickly identify potential bottlenecks or issues that may be affecting system performance.
Explanation
The gtop command displays a system monitoring dashboard in the terminal. It provides real-time information about various aspects of the system, including CPU, memory, disk, and network usage, as well as system load and process listing.

2: Sort by CPU usage
gtop
Then press c.
Motivation
The motivation for using this command is to sort the process listing in the gtop dashboard according to CPU usage. By sorting processes based on CPU usage, users can quickly identify any processes that are consuming excessive CPU resources and potentially impacting system performance.
Explanation
The c key can be pressed while running gtop to sort the process listing by CPU usage in descending order.
