3.1 Commands

Commands are not distinguished from options except for the fact that only one command is allowed.

--version
Print the program version and licensing information. Note that you cannot abbreviate this command.
--help, -h
Print a usage message summarizing the most useful command-line options. Note that you cannot abbreviate this command.
--dump-options
Print a list of all available options and commands. Note that you cannot abbreviate this command.
--server
Run in server mode and wait for commands on the stdin. The default mode is to create a socket and listen for commands there. This is only used for testing.
--daemon
Run in background daemon mode and listen for commands on a socket. This is the way dirmngr is started on demand by the other GnuPG components. To force starting dirmngr it is in general best to use gpgconf --launch dirmngr.
--supervised
Run in the foreground, sending logs to stderr, and listening on file descriptor 3, which must already be bound to a listening socket. This is useful when running under systemd or other similar process supervision schemes. This option is not supported on Windows.
--list-crls
List the contents of the CRL cache on stdout. This is probably only useful for debugging purposes.
--load-crl file
This command requires a filename as additional argument, and it will make Dirmngr try to import the CRL in file into it's cache. Note, that this is only possible if Dirmngr is able to retrieve the CA's certificate directly by its own means. In general it is better to use gpgsm's --call-dirmngr loadcrl filename command so that gpgsm can help dirmngr.
--fetch-crl url
This command requires an URL as additional argument, and it will make dirmngr try to retrieve and import the CRL from that url into it's cache. This is mainly useful for debugging purposes. The dirmngr-client provides the same feature for a running dirmngr.
--shutdown
This commands shuts down an running instance of Dirmngr. This command has currently no effect.
--flush
This command removes all CRLs from Dirmngr's cache. Client requests will thus trigger reading of fresh CRLs.
