This CLI tool allows you to send a prompt to OpenAI's GPT-4 model and receive a response directly from the command line. It uses axios for HTTP requests, yargs for command line argument parsing, and dotenv for environment variable management.

• Node.js
• npm (Node Package Manager)
• OpenAI API key

1.) Clone the repository:

git clone https://github.com/yourusername/chatgpt-cli-tool.git
cd chatgpt-cli-tool

2.) Install the required dependencies:

npm install

3.) Create a .env file in the root directory and add your OpenAI API key:

OPENAI_API_KEY=your_openai_api_key_here

To use the CLI tool, run the following command in this format:

node index.js -p "Enter prompt here"

node index.js -p "Explain the concept of recursion in computer science."

-p, --prompt: The prompt to send to ChatGPT. This option is required. -h, --help: Show help information.

Response from ChatGPT:
Choice 1: Recursion in computer science is a method where the solution to a problem depends on solutions to smaller instances of the same problem. A recursive function calls itself with modified parameters, allowing the problem to be solved in a step-by-step    manner until a base case is reached.

If the OpenAI API key is not found in the environment variables, the tool will display the following error message and exit:

OpenAI API key not found. Set the OPENAI_API_KEY environment variable.

If there's an error querying the OpenAI API, the tool will display the error message and exit:

Error querying OpenAI: [Detailed error message]
