fc-cache command in Linux with Examples

Last Updated : 14 Sep, 2022

The fc-cache command in Linux scans the font directories and build font cache for applications which use fontconfig for their font handling. When no arguments are passed fc-cache scans each directory for font files readable by FreeType. A cache is created which contains properties of each font and the associated file name, this cache is further used to speed up application when using fontconfig library during boot. Synopsis:

fc-cache [ -EfrsvVh ] [ --error-on-no-fonts ] [ --force ] [ --really-force ] [ [ -y dir ] [ --sysroot dir ] ] [ --system-only ] [ --verbose ] [ --version ] [ --help ] [ dir... ]

Options:

• -E(--error-on-no-fonts): When used this option an error will be thrown if there are no fonts present in dir or directories in the configuration.
• -f(--force): When used this command there will be Force re-generation of apparently up-to-date cache files, overriding the timestamp checking.
• -r(--really-force): This option will erase all the existing cache files and rescan.
• -s(--system-only): This command will scan only the system-wide directories and omit the places located in /usr/home directory.
• -v(--verbose): Will verbose the output while in process.
• -V(--version): Will display the version and exit.

Example:

fc-cache -Ev

Note: fc-cache returns zero if cache is successfully generated else non-zero
