ps aux, ALL users running processes
top, to view info in real time. Updates 10 seconds and will also update each time you move cursor through arrow keys
Foregrounding and Backgrounding a process
For instance, you are loop printing "Hello World" and you want to start using the command line. You don't have to open a new terminal just to leave that loop printing in background. You can just do ctrl+z, rest assured when you use ps, the process will still be there.
fg is used to make the background process into foreground.
