# minishell

This project is about creating a simple shell.

## Mandatory part

We need to implement a bash that handle simple commands like

1. redirections

	- `output (ls > file)`

	- `append (echo Hail >> file)`

	- `input (< Makefile cat)`

	- `heredoc (cat << delimiter_to_stop)`

2. pipes

	- `cat Makefile | grep CFLAGS | tr ' ' '#' | wc`

3. command history

4. environment variables

5. signals

	- `ctrl-C`

	- `ctrl-D`

	- `ctrl-\`

6. $? (expand to the exit status of the most recently executed foreground pipeline)

7. builtins

	- `echo with option -n`

	- `cd with only a relative or absolute path`

	- `pwd with no options`

	- `export with no options`

	- `unset with no options`

	- `env with no options or arguments`

	- `exit with no options`

### Bonus part

- Our program has to implement

	- `&& and || with parenthesis for priorities.`

	- `Wildcards * should work for the current working directory.`

```bash

# && and || examples

echo Hello && echo Bye

wrong_command || echo right_command

```

```bash

# Wildcard example

ls *

cat *c

```

## Download
