Shell Project

This project is a simple shell implementation in C programming language, aiming to provide a command-line interface where users can interact with the system by executing commands. It supports basic functionalities such as executing commands, handling environment variables, and managing paths.

Features

• Command Execution: Users can execute various commands supported by the underlying operating system.
• Environment Variables: The shell supports environment variables and allows users to print them using the env command.
• Path Resolution: It can find the location of executable files specified by users in the PATH environment variable.

File Structure

The project is organized into several C source files:

• shell.c: Contains the main functionality and implementation of the shell.
• prompt_string.c: Provides functions related to printing the prompt string.
• print_env.c: Contains functions for printing environment variables.
• init_path.c: Functions for initializing and freeing the PATH variable.
• getcommand.c: Handles user input and parsing commands.
• find_file.c: Implements finding executable files in the PATH.
• exec_comm.c: Functions for executing commands.
• _strtok.c: Custom implementation of the strtok function for tokenizing strings.

Usage

To compile the shell, run:

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

Then, execute the compiled shell binary:

./shell

Once the shell is running, you can type commands just like in a regular terminal.

Future Improvements

• Error Handling: Enhance error handling to provide more informative error messages to users.
• Built-in Commands: Implement additional built-in commands such as cd, history, etc.
• Interactive Features: Add support for interactive features like command history, auto-completion, and customizable prompt.
