fc-cache - build font information cache files
fc-cache [ -EfrsvVh ] [ --error-on-no-fonts ] [

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.
This program follows the usual GNU command line syntax, with long options
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, overriding 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.
fc-cache returns zero if the caches successfully generated. otherwise
non-zero.
- %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.
