Yahoo Finance CLI
A Python CLI for fetching comprehensive stock data from Yahoo Finance using yfinance.
Requirements
- Python 3.11+
- uv (for inline script dependencies)
Installing uv
The script requires uv - an extremely fast Python package manager. Check if it's installed:
uv --version
If not installed, install it using one of these methods:
macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
macOS (Homebrew)
brew install uv
Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
pip (any platform)
pip install uv
After installation, restart your terminal or run:
source ~/.bashrc # or ~/.zshrc on macOS
Installation
The yf script uses PEP 723 inline script metadata - dependencies are auto-installed on first run.
# Make executable
chmod +x /path/to/skills/yahoo-finance/yf
# Optionally symlink to PATH for global access
ln -sf /path/to/skills/yahoo-finance/yf /usr/local/bin/yf
First run will install dependencies (yfinance, rich) to uv's cache. Subsequent runs are instant.
