# 42cursus_minishell

As beautiful as a shell. This project aims to create a minimal shell that can interpret and execute basic Unix operating system commands. GNU Bash 3.2 has been taken as a reference, as it is the default version on macOS for 42Madrid computers.

This recreation of Bash supports redirections (<, >, <<, >>), pipes ( | ), single and double quotes, environment variables expansion and signals such as CTRL-D, CTRL-C and CTRL-\\. Also, we had to recreate as Builtin this list of commands: echo (with -n option), cd, pwd, export, unset, env, exit.

## Disclaimer

> At [42School](https://en.wikipedia.org/wiki/42_(school)), almost every project must be written in accordance to the [Norm](https://github.com/MGuardia10/42cursus/blob/main/subjects/en/norm_en.pdf), the school's coding standard. As a result, the implementation of certain parts may appear strange and for sure had room for improvement.
