Soooooo, am I on the right track here?
1) what command shows the current running process ps x (versus ps or ps ef)
2) Four states a process can be in 1. sleeping 2. running 3. stopped 4. zombie (versus orphan zombie parent child) or (fork exec wait exit)
3) difference between for and exec fork creates an exact duplicate of parent into child but has a different PID, exec replaces all instructios in child and executes (any shorter answers?)
