ICONVCONFIG(8)                       Linux System Administration                      ICONVCONFIG(8)



NAME
       iconvconfig - create iconv module configuration cache

SYNOPSIS
       iconvconfig [options] [directory]...

DESCRIPTION
       The  iconv(3)  function internally uses gconv modules to convert to and from a character set.
       A configuration file is used to determine the needed modules for a conversion.   Loading  and
       parsing  such  a  configuration file would slow down programs that use iconv(3), so a caching
       mechanism is employed.

       The iconvconfig program reads iconv module configuration  files  and  writes  a  fast-loading
       gconv module configuration cache file.

       In  addition  to  the system provided gconv modules, the user can specify custom gconv module
       directories with the environment variable GCONV_PATH.  However,  iconv  module  configuration
       caching is used only when the environment variable GCONV_PATH is not set.

OPTIONS
       --nostdlib
              Do not search the system default gconv directory, only the directories provided on the
              command line.

       -o outputfile, --output=outputfile
              Use outputfile for output instead of the system default cache location.

       --prefix=pathname
              Set the prefix to be prepended to the system pathnames.  See  FILES,  below.   By  de‐
              fault, the prefix is empty.  Setting the prefix to foo, the gconv module configuration
              would be read from foo/usr/lib/gconv/gconv-modules and the cache would be  written  to
              foo/usr/lib/gconv/gconv-modules.cache.

       -?, --help
              Print a usage summary and exit.

       --usage
              Print a short usage summary and exit.

       -V, --version
              Print the version number, license, and disclaimer of warranty for iconv.

EXIT STATUS
       Zero on success, nonzero on errors.

FILES
       /usr/lib/gconv
              Usual default gconv module path.

       /usr/lib/gconv/gconv-modules
              Usual system default gconv module configuration file.

       /usr/lib/gconv/gconv-modules.cache
              Usual system gconv module configuration cache.
