Which command would you use to view real-time resource usage of processes?

The command that is commonly used to view real-time resource usage of processes is "top." This command provides a dynamic, live view of system processes and their resource consumption, including CPU and memory usage. When executed, "top" displays an ongoing list of processes, updating at specified intervals, which allows users to monitor the performance of their system and identify resource-heavy applications in real time.

While "htop" also serves a similar purpose, it is not part of the default installation on all systems, whereas "top" is universally available in Linux distributions. "ps" is primarily used to display a snapshot of current processes at the time of execution, but it does not provide continuous, real-time updates. "sysinfo," depending on the specific system and context, might provide general system information but does not specifically focus on live monitoring of process resource usage like "top" does. Thus, among the options, "top" is the most straightforward and widely accepted command for real-time monitoring.
