simple_shell by Neifer Amine && Inoubli Hafed

Creating a simple UNIX shell from scratch using only the c programming language.

Description

Our Shell executes commands typed in as input.

It should:

• Display a prompt and wait for the user to type a command.
• The prompt is displayed again each time a command has been executed.
• If an executable cannot be found, print an error message and display the prompt again.
• Handles errors.
• Handles the “end of file” condition (Ctrl+D).

Files

• AUTHORS - List of contributors to this repo
• README.md - The README markdown file
• shell.h - header file used throughout each file
• lol.c - the main file
• chaines.c -
• functs.c -
• token_functs.c -

Project Requirements:

• Allowed editors: vi, vim, emacs
• All your files will be compiled on Ubuntu 14.04 LTS
• Your C programs and functions will be compiled with gcc 4.8.4 using the flags -Wall -Werror -Wextra and -pedantic
• All your files should end with a new line
• A README.md file, at the root of the folder of the project is mandatory
• Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl
• No more than 5 functions per file
• All your header files should be include guarded
• Use system calls only when you need to

Compilation

Our shell can be compiled this way, with the executable:

gcc -Wall -Werror -Wextra -pedantic *.c -o .hsh

./hsh

Testing

Our shell should work like this in interactive mode:

$ ./hsh
ShellyIsHomeBabe$ ls
AUTHORS    REsADME.md  functs.c  hsh    hsh
README.md  chaines.c   header.h  lol.c  token_functs.c
ShellyIsHomeBabe$ exit

./hsh ShellyIsHomeBabe$ cat header.h #ifndef HEADER_H #define HEADER_H #include <stdlib.h> int _check(char *buffer); int _arrayMalloc(char **argv, size_t buffersize); char *_strcpy(char *dest, char *src); char *_strcat(char *dest, char *src); char *strneifer(char *token, char **argv, char *dest); int parenting(char *dest, char **argv, char **av); char *_strdup(char *str); int _strcmp(char *s1, char *s2); int bulties(char **argv, char **env); char **toky(char *token, char **argv, char *buffer); char *toky_1(char *token1, char **argv, char *dest); #endif ShellyIsHomeBabe$

### Built-in Commands

Our Shell handles 2 Built-in commands:

* **exit**
  * Type in: exit
  * Exits the shell.

* **env**
