What type of information can 'ps aux' provide about running processes?

The command 'ps aux' is a powerful tool in Linux that provides a comprehensive overview of all running processes on the system. It offers various metrics that include the user who owns the process, the process ID (PID), CPU and memory usage, the time the process has been running, and the command that started the process. Additionally, 'ps aux' displays the session and status of each process, giving insights into what each process is doing and its current state.

This capability to provide a detailed snapshot of processes makes 'ps aux' useful for system monitoring, debugging, and performance analysis. The information it generates helps users to understand not just what processes are running but also how they are affecting system resources.

In contrast, other options suggest a more limited scope of information. For instance, restricting the output to only the process name, memory usage, or system processes doesn’t capture the full range of metrics that 'ps aux' encompasses. Therefore, the correct interpretation of 'ps aux' aligns perfectly with the range of various metrics it provides, facilitating effective management and troubleshooting of system processes.
