What is the primary function of the 'ps -x' command in Linux?

The 'ps -x' command in Linux is used to display a snapshot of the current running processes for the user and for system processes not associated with any terminal. This command provides information about all processes, including those that are not attached to a terminal, which can be crucial for system administration and process management.

For instance, when you run 'ps -x', it typically shows details such as the process ID (PID), the terminal associated with each process (if applicable), the cumulative CPU and memory usage, and the command that initiated each process. This is particularly useful for identifying processes that may be consuming system resources or diagnosing issues with running applications.

The other options listed do not pertain to the function of the 'ps -x' command. While displaying network connections, managing disk usage, and monitoring system logs are important aspects of Linux system administration, they are handled by different commands and tools such as 'netstat', 'df', and 'journalctl' respectively.
