Master Linux Like a Pro: Dive into the 2025 RHEL Red Hat Challenge!

The command that provides a real-time view of system processes is indeed the top command. When executed, it displays an ongoing list of processes currently running on the system, updating every few seconds. It provides essential information such as CPU usage, memory usage, process IDs, and other vital statistics, allowing administrators to monitor system performance and manage processes effectively.

This command is particularly useful for identifying resource-hogging applications or for observing how processes behave over time. Its interactive interface allows users to sort processes based on various metrics, send signals to processes, and easily navigate through the process list, making it a powerful tool in real-time system monitoring.

While other commands like ps show a snapshot of current processes at a given moment, they do not provide the continuous, live updates that top does. Htop also offers real-time process monitoring with a more user-friendly interface and additional features, but it's not a part of all standard installations and requires separate installation. The term "busy" does not refer to a standard command in Linux for process management and does not exist in this context.
