Shell Project

Our simple shell program produce output according to a format as described below.

   * when you type a command like /bin/ls                                   
   * when you type a command with argumenst like /binl/ls -la               
   * when you type a command like ls                                        
   * when you type a command with arguments like ls -la                     
   * when you type built-it commands                                        
   * when you type enviroment commands

Prerequisites

for this simple shell you need knowledge about loops(if, else, else if, for, while) arrays, pointers, malloc, free, structs, typedef, argc-argv, PID PPID, fork, gietline strtok, stat, PATH, getenv, wait, execve

Installing

for have the code in your local machine you only need download the code files and put it into a directory and compile it with gcc compiler

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

Built With

All the code was write under ubuntu 14.04 using the compiler version gcc 4.84 for 64 bits
