118. What is a Child Process in Unix? | Node.js Child Process Explained with Examples

Ever wondered what exactly a child process is in Unix? In this video, we break it down step-by-step and show how every process on your Unix system — from bash to Node.js — is part of a process tree, with a unique PID and a parent PID.

You'll learn:

What a child process is in Unix
How processes are spawned using the shell
The concept of parent and orphan processes
How to view PIDs and PPIDs using terminal commands
How Node.js uses the child_process module
Difference between spawn and exec
How command-line arguments work in Unix and Node.js
We’ll even explore zombie processes and the kernel’s role at the root of the process tree.

👨‍💻 Great for Node.js beginners and anyone interested in understanding Unix process management better!
