1. Processes 1 : How do I launch a new separate and independent process from within an application?

3. Processes 3 : How can I create a new process that inherits handles from its parent?
4. Processes 4 : Would these three command lines produce the same output in the file listab? How would they be similar or different? Explain.
   a. ls | fgrep a | fgrep b > listab
   b. ls > list; fgrep a < list > lista; fgrep b < lista > listab; rm list lista
   c. ls > list & fgrep a < list > lista & fgrep b < lista > listab & rm list lista
5. Processes 5 : How many distinct processes are generated by the following code fragments? Briefly explain your answer. void main() { fork(); fork(); fork(); }
