fc-cache: Generate font cache files.

fc-cache

$ fc-cache

try on your machine

The fc-cache command is used to build font information caches for the fontconfig library in Linux systems.

Fontconfig is a font management library that provides a mechanism for applications to discover and access fonts available on the system. It uses a set of configuration files to define font properties, such as font paths and substitution rules.

When you run the fc-cache command, it scans the font directories on your system (specified in the fontconfig configuration files) and creates or updates the font cache files. These cache files contain information about available fonts, their characteristics, and their locations on the file system.

The font cache files are typically stored in the /var/cache/fontconfig/ directory and have file names ending with the .cache-<version> extension, where <version> represents the version of the fontconfig library being used.

By generating and updating these font caches, fontconfig-enabled applications can quickly retrieve font information and perform font matching, which is crucial for rendering text correctly and efficiently.
