Simple Shell

This is a basic Unix shell implemented in C, designed for simple command execution. It follows strict criteria outlined below:

Features

  • Command Execution: The shell accepts one-word commands with optional arguments.

  • Prompt Display: A prompt is displayed, waiting for the user to enter a command. After execution, the prompt is displayed again.

  • Error Handling: If an executable cannot be found, an error message is displayed, and the prompt reappears.

  • End of File Handling: The shell gracefully handles the "end of file" condition (Ctrl+D).

  • Built-in Commands:

    • exit: Allows you to exit the shell.
    • env: Displays the current environment.

Getting Started

  1. Clone the Repository:
git clone https://github.com/yourusername/simple-unix-shell.git
  1. Compile the Code:
cd simple-unix-shell
gcc shell.c -o shell
  1. Run the Shell:
./shell
