What information does the 'ps aux' command provide?

The 'ps aux' command is a commonly used utility in Linux that provides detailed information about all running processes on the system. This command displays a variety of information for each process, including the process ID (PID), the user who owns the process, CPU and memory usage, the command that started the process, and the time the process has been running. The 'a' option allows users to view processes for all users, the 'u' option provides a user-oriented format, and the 'x' option shows processes not attached to a terminal. This comprehensive output allows system administrators and users to monitor and manage processes effectively.

In contrast, the other options focus on different aspects of system monitoring. For instance, system memory and disk space are examined using commands such as 'free' and 'df', respectively. Similarly, system uptime is checked with the 'uptime' or 'top' commands. Thus, these are not addressed by the 'ps aux' command, which is specifically tailored for process management and monitoring.
