What does the 'ps' command display?

The 'ps' command is used in Linux to display currently running processes on the system. When executed, it provides information about the processes that are active at that moment, including details such as process ID (PID), user ownership, CPU usage, memory usage, and command that started the process. This is invaluable for system administrators and users who want to monitor and manage processes, diagnose issues, or understand resource consumption on the system.

The other options are related to different system functionalities; for instance, network status is monitored using commands like 'ifconfig' or 'netstat', the current working directory is shown using the 'pwd' command, and memory usage can be observed with commands like 'free' or 'top'. Each of these serves a distinct purpose in system management, further emphasizing that 'ps' specifically focuses on displaying processes.
