Minishell

Minishell is a simple shell program developed as a project for the 42 school's curriculum. The aim of this project is to implement a basic shell program capable of executing basic commands and managing environment variables.

Features

Minishell supports the following features:

• Execution of basic commands (ls, echo, pwd, cat, etc.)
• Basic redirections (e.g., >, <, >>)
• Environment variables management (export, unset)
• Basic signal handling (ctrl+C, ctrl+D)
• Pipes ( | )

Getting Started

To get started with Minishell, follow these steps:

1. Clone this repository to your local machine:

git clone https://github.com/jakobklocker/minishell_42.git

2. Navigate to the project directory:

cd minishell_42

3. Build the program:

make

4. Run the program:

./minishell

Usage

Once you have launched the program, you can enter basic commands as you would in a regular shell. Minishell supports a number of built-in commands, such as echo, cd, pwd, export, unset, and env. To execute a command, simply enter it at the prompt and press enter:

$ echo Hello, World!
Hello, World!

Minishell also supports basic redirections. For example, to redirect the output of a command to a file, use the > operator:

$ echo Hello > hello.txt

This will create a new file called hello.txt and write the output of the echo command to it.

Pipes work as they do in the offical shell, creating one child process each pipe

$ ls | grep mini
