Minishell

Minishell is a school 42 project that consists of recreating a basic shell, taking bash as a reference. This project was done by @crigonza and @ipaelo, two students passionate about programming and learning.

Objectives

The objective of this project is to learn about the functioning of a shell, from reading and analyzing the user input, to executing and controlling the processes. It also aims to develop skills such as code organization, teamwork and use of tools such as git and makefile.

Features

Minishell is able to:

• Read and evaluate simple commands, with their arguments and options.
• Handle environment variables, with the commands export, unset and env.
• Execute external programs, looking for them in the PATH variable.
• Use redirections <, > and >>, as well as pipes |.
• Implement the builtins echo, cd, pwd and exit.
• Manage signals ctrl-C, ctrl-D and ctrl-\.
• Expand variables with $.

Installation

To compile minishell, just clone this repository and run the command make:

git clone https://github.com/crigonza/minishell.git
cd minishell
make

This will generate an executable called minishell, which can be launched with:

./minishell

Usage

Minishell works similarly to bash, but with some differences. For example, it does not support special characters \, ;, * or ?. It also does not allow the use of aliases, functions or scripts.

To exit minishell, you can use the command exit or the key combination ctrl-D.
