NAME
       fc-cache - build font information cache files

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


DESCRIPTION
       fc-cache scans the font directories on the system and builds font
       information cache files for applications using fontconfig for their
       font handling.

       If directory arguments are not given, fc-cache uses each directory in
       the current font configuration. Each directory is scanned for font
       files readable by FreeType.  A cache is created which contains
       properties of each font and the associated filename.  This cache is
       used to speed up application startup when using the fontconfig library.

       Note that fc-cache must be executed once per architecture to generate
       font information customized for that architecture.

OPTIONS
       This program follows the usual GNU command line syntax, with long
       options starting with two dashes (`-').	A summary of options is
       included below.

       -E --error-on-no-fonts
	      Raise an error if there are no fonts in dir or directories in
	      the configuration if not given.

       -f --force
	      Force re-generation of apparently up-to-date cache files,
	      overriding the timestamp checking.

       -r --really-force
	      Erase all existing cache files and rescan.

       -s --system-only
	      Only scan system-wide directories, omitting the places located
	      in the user's home directory.

       -v --verbose
	      Display status information while busy.

       -y -sysroot dir
	      Prepend dir to all paths for scanning.

       -h --help
	      Show summary of options.

       -V --version
	      Show version of the program and exit.

       dir    Directory to scan for fonts.

RETURN CODES
       fc-cache returns zero if the caches successfully generated. otherwise
       non-zero.

FILES
       %cachedir%/*-%arch%.cache-%version%
	      These files are generated by fc-cache and contain maps from file
	      names to font properties. They are read by the fontconfig
	      library at application startup to locate appropriate fonts.
