Once the shell returns the list, you can press the following keys to interact with it: Keys That means you’ll see real-time updates for CPU usage and running time. Unlike the ps command, the output of the top command is updated periodically. Therefore, unlike the Windows task manager, the results are static. The ps (process statuses) command produces a snapshot of all running processes. Ps command provides static snapshot of all processes, while top and htop sorts by CPU usage. To list processes in Linux, use one of the three commands: ps, top or htop. Regardless of the case, all these tasks require you to do the same thing: listing the running processes on Linux. Alternatively, times when you may want to change the priority level of a process, so the system will allocate more resources to it.
