+# Minishell - École 42
+
+## Description
+Minishell est un projet de l'École 42 qui consiste à créer un shell Unix minimaliste mais fonctionnel, similaire à bash. Ce projet permet de comprendre en profondeur le fonctionnement des shells, la gestion des processus, et l'exécution de commandes sous Unix.
+
+## Objectifs pédagogiques
+- Maîtriser la **programmation système** Unix/Linux
+- Comprendre l'**exécution de processus** (fork, exec, wait)
+- Gérer les **pipes et redirections** d'I/O
+- Implémenter un **parser** pour analyser les commandes
+- Traiter les **signaux système** (SIGINT, SIGQUIT)
+- Gérer les **variables d'environnement**
+
+## Fonctionnalités implémentées
+
+### Built-ins
+- `echo` avec option `-n`
+- `cd` avec chemins relatifs et absolus
+- `pwd` - affichage du répertoire courant
+- `export` - définition de variables d'environnement
+- `unset` - suppression de variables
+- `env` - affichage de l'environnement
+- `exit` - fermeture du shell avec code de retour
+
+### Fonctionnalités shell
+- **Exécution de programmes** via PATH ou chemin absolu
+- **Pipes** (`|`) pour chaîner les commandes
+- **Redirections** :
+  - `<` redirection d'entrée
+  - `>` redirection de sortie
+  - `>>` redirection de sortie en mode append
+  - `<<` here document avec délimiteur
+- **Variables d'environnement** (`$VAR`, `$?`, `$$`)
+- **Gestion des quotes** simples et doubles
+- **Historique** des commandes
+- **Autocomplétion** basique
+
+### Gestion des signaux
+- `Ctrl+C` (SIGINT) - interruption
+- `Ctrl+D` (EOF) - fermeture propre
+- `Ctrl+\` (SIGQUIT) - ignoré en mode interactif
+
+## Technologies utilisées
+- **Langage** : C (norme 42)
+- **Bibliothèques** : readline, termcap
+- **Appels système** : fork, execve, wait, pipe, dup2
+- **Gestion mémoire** : malloc, free (pas de leaks)
+

+```
+
+### Flux d'exécution
+1. **Lecture** de la ligne de commande (readline)
+2. **Tokenisation** et analyse lexicale
+3. **Parsing** et construction de l'AST
+4. **Expansion** des variables et wildcards
+5. **Exécution** avec gestion des processus
+6. **Nettoyage** mémoire et gestion d'erreurs
+
+## Installation et compilation
+
+### Prérequis
+- **GCC** compiler
+- **Make**
+- **Bibliothèque readline** (`sudo apt-get install libreadline-dev`)
+
+### Compilation
+```bash
+git clone <repository-url>
+cd Minishell
+make
+```
+
+### Nettoyage
+```bash
+make clean     # Supprime les fichiers .o
+make fclean    # Supprime tout + l'exécutable
+make re        # Recompile entièrement
+```
+
+## Utilisation
+
+### Lancement
+```bash
+./minishell
+```
+
+### Exemples de commandes
+```bash
+# Commandes simples
+$ ls -la
+$ pwd
+$ echo "Hello World"
+
+# Pipes
+$ cat file.txt | grep "pattern" | wc -l
+$ ls | head -5
+
+# Redirections
+$ echo "test" > output.txt
+$ cat < input.txt
+$ ls >> log.txt
+
+# Here document
+$ cat << EOF
+> line 1
+> line 2
+> EOF
+
+# Variables d'environnement
+$ export MY_VAR="value"
+$ echo $MY_VAR
+$ echo $?    # Code de retour dernière commande
+$ echo $$    # PID du shell
+
+# Built-ins
+$ cd /home/user
+$ pwd
+$ env | grep PATH
+$ unset MY_VAR
+$ exit 0
+```
+
+### Gestion des quotes
+```bash
+$ echo "Hello $USER"        # Expansion dans les doubles quotes
+$ echo 'Hello $USER'        # Pas d'expansion dans les simples quotes
+$ echo "He said 'hello'"    # Imbrication de quotes
+```
+
+## Gestion d'erreurs
+
+### Types d'erreurs gérées
+- **Commandes introuvables** (command not found)
+- **Permissions insuffisantes** (permission denied)
+- **Fichiers inexistants** (no such file or directory)
+- **Erreurs de syntaxe** (syntax error)
+- **Erreurs de pipe** (broken pipe)
+- **Allocation mémoire** (malloc failure)
+
+### Codes de retour
+- `0` - Succès
+- `1` - Erreur générale
+- `2` - Erreur de syntaxe
+- `126` - Permission refusée
+- `127` - Commande introuvable
+- `130` - Interruption par signal
+
+## Parsing et analyse
+
+### Étapes du parsing
+1. **Tokenisation** : Division en tokens (mots, opérateurs)
+2. **Classification** : Identification du type de chaque token
+3. **Validation syntaxique** : Vérification de la grammaire
+4. **Construction AST** : Arbre syntaxique abstrait
+5. **Expansion** : Variables, quotes, wildcards
+
+### Grammaire simplifiée
+```
+command_line : pipeline
+pipeline     : command ('|' command)*
+command      : simple_command redirection*
+simple_command : word word*
+redirection  : '<' word | '>' word | '>>' word | '<<' word
+```
+
+## Gestion mémoire
+
+### Stratégies appliquées
+- **Allocation tracking** : Suivi de toutes les allocations
+- **Cleanup systématique** : Libération en cas d'erreur
+- **Valgrind clean** : Aucun leak détecté
+- **Error handling** : Gestion robuste des échecs malloc
+
+## Tests et validation
+
+### Tests automatisés
+```bash
+# Tests de base
+make test
+
+# Tests avec valgrind
+make test_memory
+
+# Tests de régression
+make test_all
+```
+
+### Cas de test couverts
+- Commandes simples et complexes
+- Pipes multiples
+- Redirections combinées
+- Gestion d'erreurs
+- Variables d'environnement
+- Signaux et interruptions
+
+## Optimisations
+
+### Performance
+- **Parser optimisé** pour les cas courants
+- **Gestion mémoire** efficace
+- **Exécution directe** des built-ins
+- **Cache PATH** pour les exécutables
+
+### Compatibilité
+- **POSIX compliance** pour les fonctionnalités de base
+- **Bash-like behavior** pour l'expérience utilisateur
+- **Cross-platform** (Linux, macOS)
+
+## Compétences développées
+- **Programmation système** avancée Unix/Linux
+- **Gestion des processus** et communication inter-processus
+- **Parsing** et analyse syntaxique
+- **Architecture logicielle** modulaire
+- **Debugging** multi-processus
+- **Gestion mémoire** rigoureuse sans leaks
+- **Tests** et validation de systèmes complexes
+
+## Contraintes et normes 42
+- **Norme de codage** 42 strictement respectée
+- **Pas de variables globales** (sauf une pour les signaux)
+- **Gestion d'erreurs** exhaustive
+- **Pas de memory leaks** (validé Valgrind)
+- **Fonctions autorisées** uniquement celles de la liste 42
+
+## Challenges techniques
+
+### Difficultés rencontrées
+- **Parsing complexe** avec gestion des quotes et échappements
+- **Gestion des signaux** dans un contexte multi-processus
+- **Race conditions** entre processus père et fils
+- **Memory management** dans un contexte d'erreurs multiples
+- **Compatibilité bash** pour les edge cases
+
+### Solutions apportées
+- **Architecture modulaire** facilitant la maintenance
+- **Error handling** centralisé et robuste
+- **Tests exhaustifs** couvrant les cas limites
+- **Documentation** du code pour la compréhension
