# Minishell

> The objective of this project is for you to create a simple shell. Yes, your little bash or zsh. You will learn a lot about processes and file descriptors.

This is a group project done with [@adelcor](https://github.com/adelcor).

The shell must:

- interpret quotes correctly

- expand environment variables, including `$?`

- detect syntax errors

- have a prompt with a working history

- execute builtins, such as `echo`, `cd`, `pwd`, `export`, `unset`, `env`, and `exit`

- interpret simple and double quotes

- execute redirections (`<`, `>`, `<<`, `>>`)

- execute pipes

- Catch `ctrl-C`, `ctrl-D`, and `ctrl-\` signals

## Run the program

### Unix

Clone the repository and open it

```

# You might need to run this on MacOs

brew install readline

make

./minishell

```
