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.

The minishell program comes with a Makefile that includes the following rules:
all: compiles the program.re: recompiles the program.clean: removes obj directory with objects files.fclean: removes obj directory with objects files and minishell binary.
At 42School, almost every project must be written in accordance to the Norm, the school's coding standard. As a result, the implementation of certain parts may appear strange and for sure had room for improvement.
