Which command is used to list all running processes along with their additional information?

The command that lists all running processes along with their additional information is ps aux. This command is a popular way to view a snapshot of all current processes on a Linux system.

When you use ps aux, it provides detailed output for every process, including the user who owns the process, the process ID (PID), CPU and memory usage, the start time of the process, and the command that was used to start the process. The a option tells the ps command to show processes for all users, not just the current user. The u option displays the processes in a user-oriented format, which is helpful for understanding who is running what. The x option includes processes that are not associated with a terminal, providing a complete overview of all processes.

In contrast, other commands such as top also list running processes but present them in a continuously updating interface rather than a static snapshot. The kill command is used to terminate processes rather than list them, and systemctl is mainly focused on managing systemd services and units. Thus, ps aux is the most appropriate choice for listing all running processes with comprehensive details.
