🐚 minishell

minishell is a minimal Unix shell implemented in C as part of the 42 curriculum. It replicates core features of Bash, including command parsing, execution, environment variable handling, and redirections. This repository contains the mandatory part of the project and optionally includes bonus features.

---

💻 How It Works

• Displays a prompt and waits for user input.
• Parses and executes commands with arguments.
• Handles built-in commands like cd, echo, and export.
• Supports piping, redirections, and environment variables.
• Implements signal handling to behave like Bash.

📋 Features

Mandatory

• Custom prompt and command input via readline.
• Built-in commands:
  • echo [-n]
  • cd [path]
  • pwd
  • export

• Redirections:
  • Input <

  • Append >>
  • Here-document <<
• Piping (|) between commands.
• Environment variable expansion ($VAR, $?).
• Proper signal handling (ctrl-C, ctrl-D, ctrl-\).
