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 configura-
tion 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.
