NAME
fc-cache - build font information cache files
SYNOPSIS
fc-cache [ -EfrsvVh ] [ --error-on-no-fonts ] [ --force ] [ --re-
ally-force ] [ [ -y dir ] [ --sysroot dir ] ] [ --system-only ] [
--verbose ] [ --version ] [ --help ] [ dir... ]
DESCRIPTION
fc-cache scans the font directories on the system and builds font in-
formation 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 proper-
ties 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 op-
tions starting with two dashes (`-'). A summary of options is included
below.
-E Raise an error if there are no fonts in dir or directories in
the configuration if not given.
-f Force re-generation of apparently up-to-date cache files, over-
riding the timestamp checking.
-r Erase all existing cache files and rescan.
-s Only scan system-wide directories, omitting the places located
in the user's home directory.
-v Display status information while busy.
-y Prepend dir to all paths for scanning.
-h Show summary of options.
-V 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 li-
brary at application startup to locate appropriate fonts.
