Linux "iconvconfig" Command Line Options and Examples

create iconv module configuration cache

The iconv(3) function internally uses gconv modules to convert to and from a character set. A configuration file is used to deter‐ mine 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.

Usage:

iconvconfig [options] [directory]...

Command Line Options:

--nostdlib

Do not search the system default gconv directory, only the directories provided on the command line.


                            iconvconfig --nostdlib ...

-o

Use outputfile for output instead of the system default cache location.


                            iconvconfig -o ...

--prefix

Set the prefix to be prepended to the system pathnames. See FILES, below. By default, the prefix is empty. Setting the pre‐fix to foo, the gconv module configuration would be read from foo/usr/lib/gconv/gconv-modules and the cache would be writtento foo/usr/lib/gconv/gconv-modules.cache.


                            iconvconfig --prefix ...

Print a usage summary and exit.


                            iconvconfig -? ...

--usage

Print a short usage summary and exit.


                            iconvconfig --usage ...

-V

Print the version number, license, and disclaimer of warranty for iconv.EXIT STATUSZero on success, nonzero on errors.FILES/usr/lib/gconvUsual default gconv module path./usr/lib/gconv/gconv-modulesUsual system default gconv module configuration file./usr/lib/gconv/gconv-modules.cacheUsual system gconv module configuration cache.
