fc-query extracts and displays information from font files without installing them. It's part of fontconfig and shows font properties like family, style, weight, and supported languages.The tool queries individual font files directly rather than the system font cache.

For font collections (.ttc), specific fonts can be selected by index.fc-query is useful for examining fonts before installation or scripting font management tasks.
