While I was working on a project at Holberton Coding School, I tackled a challenge that was both exciting and terrifying: building a simple shell in C. I am studying hard. fork(), exec()and environment variables like they’re the coolest puzzles on the planet. Spoiler alert: they totally are.
This shell doesn’t just read commands, it starts new processes, handles errors, and exposes custom built-ins. Every bug eliminated feels like a level up in a coding RPG. Sure, there were frustrating moments (imagine me googling at 2am 💩), but watching my shell come to life made every late-night debugging session worth it. If you want a crash course in how operating systems can really work their magic, building a simple shell from scratch is the ultimate option. Just don’t forget the coffee. Happy coding!
