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 only used 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 configu‐
              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.
