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
              default, the prefix is empty.  Setting the prefix to foo, the gconv module configuā€
              ration  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, non-zero 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.
