Process creation and termination - fork(), exec(), wait() and exit()
Process Creation in UNIX: fork(), exec(), wait(), and Process Management Explained
In this video, we explore how process creation works in UNIX systems using the fork() command. We explain how parent and child processes are created, managed, and terminated. Learn the critical functions like fork(), exec(), wait(), and exit(), and how they control process execution. We also cover special cases like Zombie and Orphan Processes.
What you’ll learn:
• fork(): Creating child processes identical to the parent
• exec(): Running different programs in parent and child processes
• wait(): Suspending parent until the child completes execution
• exit(): Proper process termination and resource deallocation
• Understanding Zombie Processes: When the parent doesn’t wait for the child
• Understanding Orphan Processes: When the parent terminates before the child
