Which command would you use to list all currently running processes in Linux?

• A. ps
• B. top
• C. jobs
• D. htop

Answer: (A)

The command that lists all currently running processes in Linux is "ps." When executed without any options, the "ps" command provides a snapshot of the current processes for the user running the command. By default, it shows processes associated with the current terminal session. However, it can be used with various options to display additional information, including processes for all users and additional details about each process. While "top" and "htop" can also provide information about currently running processes, they do so in a dynamic, real-time format that continuously updates the display. This is helpful for monitoring system resource usage but does not provide a simple listing like "ps." The "jobs" command is used specifically to display the status of jobs started in the current shell session, making it less relevant for listing all running processes across the system.
