Query OpenAI's GPT from the terminal

Introduction

This script allows you to interact with OpenAI's GPT model directly from your zsh terminal. It's a quick way to get help on command syntax or any query without leaving the terminal. The script has no memory so each interaction is independent.

Setup Instructions

1. Copy this script to a directory in your $PATH. For example, cp chat.sh /usr/local/bin/.
2. Make it executable: chmod +x /usr/local/bin/chat.sh.
3. Create an alias in your bash config such as ~/.zshrc: alias chat=/usr/local/bin/chat.sh.
4. Add your OpenAI API key as an environment variable. For example, add export OPENAI_API_KEY=<your-api-key> in ~/.zshrc. API Key Instructions
5. Install jq for JSON parsing: brew install jq. Install instructions

Usage

You can prompt the script in two ways:

Method 1: Inline Prompt

chat "Your query here."

• Pros: Quick for simple queries. Allows command chaining with pipes |.
• Cons: Cannot include the same type of quotes both inside and outside the query. Use a combination of double and single quotes if necessary.

Method 2: Multiline Prompt

chat
Your query here.
Add as many lines as needed.
END

• Pros: Supports long queries and line breaks. Allows quotes inside the prompt.
• Cons: Requires manual typing of END to finish input.

Examples

1. For a quick query:

2. For a multiline query:

Notes

• 8-bit ANSI text decorations are used to decorate the response. 16-bit colors may not work in all environments. Tweak the prompt to change color decorations. It's finicky.
• Customize the system message as needed.
• TODO: Include support for light mode. (eww.) This version only works with dark themes.
