# Minishell - [@42Born2code](https://www.youtube.com/watch?time_continue=88&v=eawhnhTO2oY&feature=emb_logo)
---
## Introduction
Minishell is a group project at [42](https://www.42.fr/). The goal of this project is to create a simple shell that behave like bash.
This project was carried out by [__Jecaudal__](https://github.com/lobbyra) and [__Jereligi__](https://github.com/Jean-xavierr)
## Subject
We based on bash behavior.
__*Rules of project*__
__implement the following builtins:__
- `echo` and the `-n` option
- `cd` only with an absolute or relative path
- `pwd` without any options
- `export` without any options
- `unset` without any options
- `env` without any options or arguments
- `exit` without any options
__The function to be implemented in the project__
- Display a prompt while waiting for a new order.
- Find and launch the correct executable (based on a PATH environment variable
or using an absolute path).
- `;` in the command line must separate the commands.
- `’`and `"` must work as in bash, except multiline.
- The `<`,`>` and `>>` redirects must work as in bash, except for
aggregations of fd.
- Pipes redirections `|`.
- The environment variables ($ followed by characters) must work.
- `$?` variable.
- `ctrl-C`, `ctrl-D` and `ctrl- \` signals should have the same behavior.
This project is coded in C with our proper norm at 42.
__Project duration__ : 4 weeks
