Super Simple Shell 💻

Overview📝

Super Simple Shell is a custom Unix-like shell implemented in C. It provides a basic command-line interface to interact with the underlying operating system by executing commands, supporting standard features like argument handling, built-in commands, and error reporting.

Features⚡

• Command Execution: Executes system commands using the execvp system call.
• Built-in Commands: Supports internal commands like cd (change directory) and exit to terminate the shell.
• Custom Prompt: Displays a prompt indicating the current working directory for better context.
• Error Handling: Provides user-friendly error messages for invalid commands and system call failures.
• Basic Input Parsing: Handles input commands and arguments efficiently.

Installation ⚙

To clone and build the project:

1. Clone the repository:

   git clone https://github.com/abhilov23/super-simple-shell.git
   cd super-simple-shell

2. Compile the shell:

   gcc -o super_simple_shell.exe cell.c utils.c -I .

3. Run the shell:

   ./super_simple_shell.exe

Usage🚀

1. Start the shell by running:

   ./super_simple_shell.exe

2. Execute commands as you would in a typical Unix shell. Examples:

   ls -l
   cd /path/to/directory
   echo "Hello, World!"

3. Use the exit command to terminate the shell:

   exit

Built-in Commands 🔧

• cd: Changes the current working directory.

  cd [directory]

• exit: Exits the shell program.

  exit

Code Structure 📂

• cell.c: Contains the main function, handles user input, and manages the shell loop.
• utils.c: Implements helper functions for command parsing, execution, and built-in commands like cd and exit.
• cell.h: Declares shared functions and constants used across the project.

Error Handling ⚠️

The shell provides detailed error messages for situations such as:

• Invalid or unknown commands.
• System call failures.
• Incorrect usage of built-in commands.

Limitations 🚧

• Advanced features like piping (|), I/O redirection (<, >), and background execution (&) are not currently supported.
• Input parsing is basic and may not handle all edge cases.

Future Enhancements 🔮

• Add support for pipelines (|) and background tasks (&).
• Improve input parsing to handle more complex command structures.
• Enhance I/O redirection functionality.
• Implement command history and tab-completion features.
