How to Use the Command 'fc-match' (with Examples)

The fc-match command is a part of the font configuration library in Linux systems, commonly used to find the best available fonts for given pattern matching criteria. It helps users and applications identify the most suitable fonts based on certain specifications, ensuring that the selected font meets both aesthetic and functional requirements. This command is particularly useful for developers and system administrators who need to manage fonts programmatically in Linux-based environments.

Use Case: Return a Sorted List of Best Matching Fonts

Code:

fc-match -s 'DejaVu Serif'

Motivation: The motivation behind using fc-match -s 'DejaVu Serif' is to find and list all the available fonts that closely match the “DejaVu Serif” font pattern, in the order of their closeness to the given pattern. This can be particularly useful for designers or programmers who are searching for a specific font but are open to alternatives. By using this command, they can effortlessly explore similar fonts that may meet their needs more effectively. This method saves time by providing a concise list of the best matches instead of manually browsing through a large number of fonts installed on a system.

Explanation:

• fc-match: This is the base command that initiates the matching process for fonts available in the system.
• -s: This argument stands for “sort.” It ensures that the matched fonts are returned in a sorted order based on how closely they match the given pattern.
• 'DejaVu Serif': This is the font pattern that the command tries to match. The pattern doesn’t have to be an exact font name; the command interprets it to find the closest matches.

Example Output: When the command is executed, it might return output similar to:

DejaVuSerif.ttf: "DejaVu Serif" "Book"
LiberationSerif-Regular.ttf: "Liberation Serif" "Regular"
NotoSerif-Regular.ttf: "Noto Serif" "Regular"
TimesNewRoman.ttf: "Times New Roman" "Regular"
...

This output presents a list of fonts ranked by their similarity to “DejaVu Serif,” starting with the closest match. Each line displays the font file, followed by its name and style, giving the user a clear view of alternative fonts available in their system.

Conclusion

The fc-match command is a powerful tool for managing and searching fonts on Linux systems. By specifying options like -s, users can gain control over how fonts are matched and sorted, allowing for quick identification of alternatives to meet their requirements. Through such command-line tools, users can streamline font management tasks, making it easier and more efficient to work with various applications and projects requiring specific typography.
