#### 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. Although they are not directories, the socket file names used by `gpg-agent` and `dirmngr` are printed as well. Note that the socket file names and the `homedir` lines are the default names and they may be overridden by command line switches.
`--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.
`--reload [`component`]`
  Reload all or the given component. This is basically the same as sending a SIGHUP to the component. Components which don't support reloading are ignored.
`--kill [`component`]`
  Kill the given component. Components which support killing are gpg-agent and scdaemon. Components which don't support reloading are ignored. Note that as of now reload and kill have the same effect for scdaemon.

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.
