What command would you use to see real-time statistics of system resources?

The command used to see real-time statistics of system resources is 'top.' This command provides a dynamic, real-time view of system processes, including CPU and memory usage, allowing users to monitor system performance as it happens.

When executed, 'top' displays a list of currently running processes along with important metrics like the percentage of CPU and memory they are consuming. It updates this information periodically, giving users a live feed of system activity, which is essential for troubleshooting and performance tuning.

While both 'htop' and 'top' can provide similar information, 'htop' is typically not installed by default on all systems and offers a more user-friendly interface. 'df' and 'free' are not designed for real-time monitoring; 'df' displays disk space usage, and 'free' provides memory usage statistics but does so in a static manner rather than in real-time. Therefore, 'top' is the appropriate choice for monitoring system resources live.
