What does the command 'top' do in Linux?

The command 'top' in Linux provides a dynamic, real-time view of system resource usage and the currently running processes. It showcases various details such as CPU usage, memory consumption, and the running state of processes, allowing users to monitor and manage system performance effectively. The interface is continuously updated, which helps administrators and users diagnose system bottlenecks, observe resource allocation, and identify processes that may be consuming excessive resources.

By displaying this vital information in real time, 'top' helps with tasks like identifying unresponsive applications, overseeing system load, and verifying whether specific processes are functioning as intended. This functionality makes it an essential tool for system administrators and anyone who needs to maintain the health and efficiency of a Linux system.
