Minishell (msh$)

Welcome to our Minishell project, developed as part of the curriculum at 42 Berlin. This project aims to build a simple shell (command interpreter) in C, mirroring the basic functionalities of bash. By implementing Minishell, we delved deep into the workings of a Unix shell, processes, file descriptors, and environment variables, enhancing our understanding of system calls and C programming.

Features

• Command Execution: Executes commands found in the PATH.
• Builtin Commands: Includes echo, cd, pwd, export, unset, env, and exit as built-in functions.
• Redirections and Pipes: Handles input/output redirections (<, >, >>) and pipes (|).
• Environment Variables: Supports setting and expanding environment variables ($VAR_NAME).
• Error Handling: Provides meaningful error messages, mirroring those from bash.
• Signal Handling: Manages signals like CTRL-C to interrupt commands, CTRL-D to exit the shell, and CTRL-\ to ignore.

Key Learnings

While there were many hurdles we came across during the course of our project, we compiled a list of the main tools and techniques that managed to push us across the finish line:

• Kanban Board / Ticketing (Notion)
• Github Feature Branches

Installation and Usage

Clone the repository and build the Minishell executable:

git clone https://github.com/eschencode/minishell.git
