Share your story βDay 55: Persist Environment Variables the Right Way
Environment variables let you configure applications without hardcoding values β but only if you persist them correctly.
# Set a variable for the current session only export API_KEY="abc123" export DATABASE_URL="postgres://localhost:5432/mydb" # Persist variables by adding to your shell profile # For bash: echo 'export API_KEY="abc123"' >> ~/.bashrc # For zsh: echo 'export API_KEY="abc123"' >> ~/.zshrc # Apply changes without restarting the terminal source ~/.bashrc # or: source ~/.zshrc # List all environment variables env printenv # Check a specific variable echo $API_KEY printenv API_KEY # Unset a variable unset API_KEY
