       dbus-send - Send a message to a message bus

       dbus-send  [--system | --session] [--dest=NAME] [--print-reply] [--type=TYPE] <destination
       object path> <message name> [contents ...]

       The  dbus-send  command	is  used  to  send  a  message	to  a  D-Bus  message  bus.   See
       http://www.freedesktop.org/software/dbus/ for more information about the big picture.

       There are two well-known message buses: the systemwide message bus (installed on many sys-
       tems as the "messagebus" service) and the per-user-login-session message bus (started each
       time  a	user  logs in).  The --system and --session options direct dbus-send to send mes-
       sages to the system or session buses respectively.  If  neither	is  specified,	dbus-send
       sends to the session bus.

       Nearly  all uses of dbus-send must provide the --dest argument which is the name of a con-
       nection on the bus to send the message to. If --dest is omitted, no destination is set.

       The object path and the name of the message to send must always	be  specified.	Following
       arguments, if any, are the message contents (message arguments).  These are given as type-
       specified values and may include containers (arrays, dicts,  and  variants)  as	described

       <contents>   ::= <item> | <container> [ <item> | <container>...]
       <item>	    ::= <type>:<value>
       <container>  ::= <array> | <dict> | <variant>
       <array>	    ::= array:<type>:<value>[,<value>...]
       <dict>	    ::= dict:<type>:<type>:<key>,<value>[,<key>,<value>...]
       <variant>    ::= variant:<type>:<value>
       <type>	    ::= string | int16 | uint 16 | int32 | uint32 | int64 | uint64 | double | byte | boolean | objpath

       D-Bus  supports	more types than these, but dbus-send currently does not.  Also, dbus-send
       does not permit empty containers or nested containers (e.g. arrays of variants).

       Here is an example invocation:

	 dbus-send --dest=org.freedesktop.ExampleName		    \
		   /org/freedesktop/sample/object/name		    \
		   org.freedesktop.ExampleInterface.ExampleMethod   \
		   int32:47 string:'hello world' double:65.32	    \
		   array:string:"1st item","next item","last item"  \
		   dict:string:int32:"one",1,"two",2,"three",3	    \
		   variant:int32:-8				    \

       Note that the interface is separated from a method or signal name by a dot, though in  the
       actual protocol the interface and the interface member are separate fields.

       The following options are supported:

	      Specify the name of the connection to receive the message.

	      Block for a reply to the message sent, and print any reply received.

	      Send to the system message bus.

	      Send to the session message bus.	(This is the default.)

	      Specify "method_call" or "signal" (defaults to "signal").
