Shell

This repository contains our own simple version of the shell, a command line interpreter written in C language.

The Flowchart shows how the program was built.

Files of this repository

File	Description
man_1_simple_shell.1	It is the manual for using the shell. Contains a description, ways for invocation, and some examples of builtins and executables that can be used inside the command line interpreter.
shell.h	It is a header file that contains all the c libraries needed for the program, the description and prototypes of all the functions, structures, builtins, printing functions, and helpers.
shell.c	It contains the entry point of the program, where the execution begins. It shows the prompt and receives the characters written in the command line.
get_line.c	It gets the string written from the command line and save it in a predefined buffer, allocating enoght space.
str_tok.c	It cuts the string in parts.
tokenize.c	It save the parts to be analyzed later.
builtins_list.c	It compare the command with a list of builtins, and if there is a match, It calls the associated builtin.
builtins.c	It contains the code of the builtins included in the program.
find_in_path.c	It analyze the global variable path.
execute.c	It tries to execute the string as a command.
helpers_string.c	It contains some functions that help the main functions to process the strings.
helpers_printing.c	It contains some functions that help to print content in the standar error and the standar output.
