🐚 Minishell

Welcome to Minishell, a simplified Unix shell implemented in C as part of the 42 school curriculum.

This project aims to replicate key features of a real shell, including command execution, redirections, pipes, environment variable handling, and more — all built from scratch with a deep understanding of system calls and process management.
