Which command would you use to view active processes in a Linux system?

The command to view active processes in a Linux system is "top." This command provides a dynamic, real-time view of system processes, displaying vital information such as CPU usage, memory usage, and the processes currently running on the system, all updating continuously. Users can interact with this interface to terminate processes or change their priority, making it a powerful tool for monitoring system performance.

While other commands like "ps" can also show processes, "top" offers a more interactive and continually updating view, which is particularly useful for users who need to monitor system resources live. The lack of interactivity in "ps" and the non-existence of commands like "list" and "proc" for viewing processes further emphasizes why "top" is the most appropriate choice for this task.
