🐚 Welcome to Our Simple_Shell. We Hatim and Omar recently completed a lightweight and efficient command-line shell program built with the C programming language! 💻

🖥️ Simple Shell provides a user-friendly interface for executing commands and managing your system. It is a restricted shell that adheres to the list of allowed functions and system calls provided below. With simplicity and efficiency in mind, Simple Shell offers a reliable shell experience while utilizing only the allowed functions and system calls.

⚡️ Simple Shell comes with the following features:

• Command execution: Enter commands and execute them seamlessly.
• Command-line arguments: Pass arguments to executables for enhanced functionality.
• Environment variable management: Easily manage environment variables for your shell sessions.
• "exit" command: Use the "exit" command to gracefully exit the shell.

🔧 Simple Shell has the following dependencies:

• main.h: Header file containing function prototypes and necessary library includes.
• main.c : Function serves as the entry point for the program. It continuously reads user input, tokenizes it, and executes the corresponding command using the aforementioned functions. The shell provides a prompt ($) to indicate readiness for user commands.
• functions.c : The file that hold the functions that will be called in the main.c.
• str.c strr.c : Files containing function definition for our own forbiden functions and system calls(strcat, strlen, ...).

⚙️ Simple Shell leverages several functions to provide its functionality:

• env: Duplicates the environment variables, ensuring seamless management.
• freeEnviron: Frees the duplicated environment variables, preventing memory leaks.
• removeTrailingNewline: Removes trailing newline characters, ensuring clean input handling.
• tokenizeCommandLine: Tokenizes command lines into individual arguments for accurate execution.
• executeCommand: Executes commands with the given arguments for efficient processing.
• performFork: Performs a fork to create child processes and execute commands within them.

The main function serves as the entry point for the program. It continuously reads user input, tokenizes it, and executes the corresponding command using the aforementioned functions. The shell provides a prompt ($) to indicate readiness for user commands.

⚙️ Here a flow chart that illustrate, in an easy way, how the our Simple_Shell works:

📋 To get started with Simple Shell, follow these steps:

1. Clone the repository and navigate to the project directory.

git clone https://github.com/RyuzakiiL23/simple_shell.git
cd simple_shell

2. Compile the program.

gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c -o hsh

3. Run the shell.

./hsh

4. Once the shell is running, you can start entering commands and executing them.

$ ls
file1.txt  file2.txt  folder1  folder2

5. Enjoy the power and convenience of Simple Shell! Feel free to explore various commands and features.

6. To exit the shell, simply use the "exit" command.

$ exit
