ICONVCONFIG(8)           Linux System Administration          ICONVCONFIG(8)

NAME         top

       iconvconfig - create iconv module configuration cache

SYNOPSIS         top

       iconvconfig [options] [directory]...

DESCRIPTION         top

       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         top

       --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 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         top

       Zero on success, nonzero on errors.

FILES         top

       /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.
