Which command is used to view running processes in Linux?

The command used to view running processes in Linux is "ps." This command is a fundamental utility that provides a snapshot of the current processes, showing details such as the process ID (PID), terminal associated with the process, the time the process has been running, and the command that started the process.

While "top" is another command that displays real-time updates of running processes in a dynamic manner, "ps" gives a static snapshot which can be useful for checking processes at a specific moment in time. On the other hand, "df" is used to report disk space usage, and "man" is utilized to access the manual pages for commands, making them irrelevant to the task of viewing running processes. Understanding the utility of these commands is essential for managing and monitoring processes effectively in a Linux environment.
