Minishell

A sleek, efficient, and professional shell implementation.

---

🚀 Overview

Minishell is a lightweight, custom-built shell developed as part of the 42 curriculum. It replicates the core functionality of bash, providing a robust environment for command execution, pipelining, and environment management.

Designed with a focus on memory efficiency and architectural clarity, Minishell serves as a deep dive into systems programming, process management, and lexical analysis.

✨ Key Features

• Built-in Commands: Optimized implementations of cd, echo, env, exit, export, pwd, and unset.
• Execution Engine: Support for multiple pipelines (|) and complex redirections (<, >, <<, >>).
• Environment Management: Dynamic tracking and expansion of environment variables.
• Signal Handling: Responsive management of SIGINT, SIGQUIT, and EOF.
• Robust Memory Management: Integrated custom garbage collector to ensure zero leaks.
