iconvconfig(8) System Manager's Manual 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 configura-
tion 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 di-
rectories provided on the command line.
--output=outputfile
-o 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.
--version
-V 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.
Depending on the architecture, the above files may instead be located
at directories with the path prefix /usr/lib64.
