Minishell

The existence of shells is linked to the very existence of IT. At the time, all coders agreed that communicating with a computer using aligned 1/0 switches was seriously irritating. It was only logical that they came up with the idea to communicate with a computer using interactive lines of commands in a language somewhat close to english.The objective of this project is to create a simple shell using c.

The Project consist of two parts :

Parsing

    1. readline
    2. pipes
    3. Command and arguments
    4. Protections
    5. The <,>, >> redirects
    6. Environment variables
    7. The separations
    8. history

The execution

    1. Redirects
    2. Env, export, unset
    3. Exit and $?
    4. Pipes / signals / process links 

Installation

Use the Makrfile

Make

Usage

./minishell
