Which command is used to view the current running processes in Linux?

The command to view the current running processes in Linux can indeed encompass all of the provided options. Each command serves a similar purpose but with different levels of detail and interactivity.

The 'ps' command is used to display information about running processes. By default, it shows processes running in the current shell session. Various options can be added to 'ps' to modify the output and include more details or processes from all users.

The 'top' command provides a dynamic, real-time view of running processes, updating every few seconds. It displays system summary information and the active processes, allowing the user to monitor system performance, CPU usage, memory usage, and other metrics in a continuously updated format.

The 'htop' command is a more visually appealing and user-friendly alternative to 'top'. It provides a similar real-time overview, but with additional features like color coding and the ability to interactively manage processes (such as killing them) using keyboard shortcuts.

Since all three commands can be utilized to view current running processes, the correct answer encompasses them all, making it a comprehensive choice for monitoring processes in Linux systems.
