minishell

Summary

This project challenged us to make our own shell. It is basically a reduced version of the Bash shell (a humbly little version of that) written in C. It provides a simple and minimalistic command-line interface for users to interact with the operating system. Developed in pair with @0xEDU.

Features

• Simple command-line interface
• Command history
• Built-in commands: cd, pwd, export, unset, env, exit, echo
• Command execution with arguments
• Multiple command execution with pipes: |
• Redirecting operators: <, >, >> and <<
• Environment variable expansion: $
• Signal handling: CTRL-C, CTRL-D

Getting Started

Prerequisites

To compile and run Minishell, you'll need a C compiler and the GNU Readline library. The following instructions assume you are using a Unix-based system, such as Linux or macOS.

Compilation

1. Clone the repository:

git clone https://github.com/Guiribei/my_shell.git

2. Change to the repository directory:

cd my_shell

3. Compile the project using the provided Makefile:

make

Running Minishell

After successful compilation, you can run Minishell by executing the generated binary:

./minishell

You will be greeted with a colored command prompt, where you can start entering commands.

+minishell:~$

Example Usage

Here's a quick example of what you can do with Minishell:

minishell:~/home/user/my_shell$ echo "Hello, World!"
Hello, World!
minishell:~/home/user/my_shell$ ls
includes  libft  Makefile  minishell  objects  sources
minishell:~/home/user/my_shell$ exit

Limitations

Minishell is a reduced version of Bash, and as such, it does not support all features available in a full-featured shell. Some of the missing features include:

• Command separators as ; and &&
• Scripting capabilities
• Customization and extensibility
• Wildcards
