What command displays processes currently running on a Linux system along with their resource usage?

The command that displays processes currently running on a Linux system, along with their resource usage, is the 'top' command. This tool provides a dynamic, real-time view of system processes and their consumption of system resources, including CPU and memory usage. When executed, 'top' updates the display periodically, which allows users to monitor process activity and resource utilization actively.

In contrast, while 'ps' prompts a snapshot of processes at a specific moment, it doesn’t provide real-time updates. Similarly, 'htop' does also show processes and resource usage, but it is a more advanced version of 'top' and may not be available in all distributions by default. The 'jobs' command lists background processes associated with the current shell session but lacks the comprehensive details on resource usage and real-time information that is characteristic of 'top'.
