Which command would you use to display all processes with their scheduling priorities?

The command that displays all processes along with their scheduling priorities is the "top" command. When executed, "top" presents a dynamic, real-time view of system processes, including details such as CPU usage, memory usage, process IDs, and crucially, the priority of each process, referred to as the "PR" column in its output. This real-time monitoring provides an ongoing visual representation of how processes are performing and their impact on system resources.

The other commands, while useful in their own right, serve different purposes. For instance, "ps" is typically used for snapshotting current processes, but it does not continuously update and lacks the dynamic nature and real-time prioritization display that "top" provides. "htop" also displays processes with their priorities and allows for easier interaction, but it may not come pre-installed on all systems. "pstree" focuses on showing processes in a tree-like structure to illustrate parent-child relationships rather than displaying scheduling priorities in a straightforward manner. Thus, for the specific need of displaying all processes with their scheduling priorities, "top" is the most appropriate choice.
