MiniShell

My 8th project at the 42sp and the most huge one rsrs. This is the first project that i do with a partner, that was Jhonatam estevam lima, and was so cool training my teamwork skills with him.

Introduction

The existence of shells is linked to the very existence of IT. At the time, all coders agreed that communicating with a computer using aligned 1/0 switches was seriously irritating. It was only logical that they came up with the idea to communicate with a computer using interactive lines of commands in a language somewhat close to english. With Minishell, you’ll be able to travel through time and come back to problems people faced when Windows didn’t exist.
