A Throwback to My Holberton Days: Crafting a Simple Shell in C

This content originally appeared on DEV Community and was authored by Aryam Michel

Back when I was knee-deep in projects at Holberton Coding School, I tackled a challenge that felt equal parts exhilarating and terrifying: building a Simple Shell in C. Picture me, a coffee-fueled student, poring over fork(), exec(), and environment variables like they were the coolest puzzles on Earth. Spoiler alert: they totally were.

This Shell went beyond just reading commands—it spun up new processes, handled errors, and showcased custom built-ins. Every bug squashed felt like leveling up in a coding RPG. Sure, there were moments of frustration (picture me Googling 💩 at 2 AM), but watching my Shell come to life was worth every late-night debugging session. If you ever want a crash course in how operating systems really do their magic, building a Simple Shell from scratch is the ultimate ride. Just don’t forget the coffee. Happy coding!
