Minishell - 42 Project

---

Introduction

Minishell is a 42 project that involves creating a simplified version of a Unix shell. The goal is to understand how shells work by implementing features like command execution, pipes, redirections, and environment variable management.

---

Overview

This project requires you to build a basic shell that can interpret and execute commands, handle pipelines, and manage file redirections. It also includes features like environment variable expansion and signal handling.

---

Requirements

• The program must be written in C.
• The program must handle command execution, pipes (|), and redirections (>, <, >>).
• The program must manage environment variables ($VAR).
• The program must handle signals like Ctrl-C and Ctrl-D.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/minishell.git
   cd minishell

2. Compile the program using make:

  make
  The executable minishell will be generated.

Usage

Run the program with the following command:

./minishell

Once inside the shell, you can execute commands like:

ls -la | grep .c
echo $HOME > output.txt

Features

Command execution (e.g., ls, echo).

Pipes (|) and redirections (>, <, >>).

Environment variable expansion ($VAR).

Signal handling (Ctrl-C, Ctrl-D).
