7.4.1 Invoking gpgconf

One of the following commands must be given:

--list-components

List all components. This is the default command used if none is specified.

--check-programs

List all available backend programs and test whether they are runnable.

--list-options component

List all options of the component component.

--change-options component

Change the options of the component component.

--check-options component

Check the options for the component component.

--apply-defaults

Update all configuration files with values taken from the global configuration file (usually /etc/gnupg/gpgconf.conf).

--list-dirs

Lists the directories used by gpgconf. One directory is listed per line, and each line consists of a colon-separated list where the first field names the directory type (for example sysconfdir) and the second field contains the percent-escaped directory.

--list-config [filename]

List the global configuration file in a colon separated format. If filename is given, check that file instead.

--check-config [filename]

Run a syntax check on the global configuration file. If filename is given, check that file instead.

The following options may be used:

-v

--verbose

Outputs additional information while running. Specifically, this extends numerical field values by human-readable descriptions.

-n

--dry-run

Do not actually change anything. This is currently only implemented for --change-options and can be used for testing purposes.

-r

--runtime

Only used together with --change-options. If one of the modified options can be changed in a running daemon process, signal the running daemon to ask it to reparse its configuration file after changing.

This means that the changes will take effect at run-time, as far as this is possible. Otherwise, they will take effect at the next start of the respective backend programs.
