Most people think their terminal directly runs commands. That’s not what’s happening.
In this video, I break down what actually happens when you press Enter in a Linux shell at the system call level.
We go through: - how fork() creates a new process - how execve() replaces it with your command - how the kernel actually executes programs - and why your terminal never really “runs” anything directly
If you’ve ever used Linux, Bash, or worked with systems, this will change how you think about commands entirely.

NEW VIDEO: I built Docker from scratch using only bash
Ever wondered how containers actually work? I spent the weekend building a minimal container runtime to find out.
Turns out, it's just Linux namespaces + chroot. No magic.
The full script is 40 lines. The video is 45 minutes of me explaining every single line.
Watch if you want to actually understand containers instead of just using them 👇
