15.25.2. Synopsis

taler-config [-b backend | –supported-backend=backend] [-c filename | –config=filename] [-f | –filename] [-F | –full] [-h | –help] [-L loglevel | –loglevel=loglevel] [-l filename | –logfile=filename] [-o option | –option=option] [-r | –rewrite] [-S | –list-sections] [-s section | –section=section] [-V value | –value=value] [-v | –version]

15.25.3. Description

taler-config can be used to read or modify GNU Taler configuration files.

-b BACKEND | –supported-backend=BACKEND

Tests whether the specified BACKEND is supported by the current installation. The backend must match the name of a plugin, i.e. “namestore_postgres” for the PostgreSQL database backend of the “NAMESTORE” service. If BACKEND is supported, taler-config will return a status code of 0 (success), otherwise 77 (unsupported). When this option is specified, no other options may be specified. Specifying this option together with other options will cause taler-config to return a status code of 1 (error).


Use the configuration file FILENAME.

-f | –filename

Try to perform expansions as if the option values represent filenames (will also be applied even if the option is not really a filename).

-F | –full

Write the full configuration file, not just the differences to the defaults.

-h | –help

Print short help on options.


Use LOGLEVEL for logging. Valid values are DEBUG, INFO, WARNING, and ERROR.


Send logging output to FILENAME.

-o OPTION | –option=OPTION

Which configuration option should be accessed or edited. Required to set a value. If not given, all values of a given section will be printed in the format “OPTION = VALUE”.

-r | –rewrite

Write the configuration file even if nothing changed. Will remove all comments!

-S | –list-sections

List available configuration sections for use with --section.

-s SECTION | –section=SECTION

Which configuration section should be accessed or edited. Required option.

-V VALUE | –value=VALUE

Configuration value to store in the given section under the given option. Must only be given together with -s and -o options.


Changing the configuration file with -V will remove comments and may reorder sections and remove @INLINE@ directives. Using -V is thus dangerous! Use with extreme caution!

-v | –version

Print GNU Taler version number.
