NAME
       dbus-send - Send a message to a message bus

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

DESCRIPTION
       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  systems 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 messages 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 connection 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	 (mes‐
       sage  arguments).   These  are  given  as type-specified values and may
       include containers (arrays, dicts, and variants) as described below.

       <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				    \
		   objpath:/org/freedesktop/sample/object/name

       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 mem‐
       ber are separate fields.

OPTIONS
       The following options are supported:

       --dest=NAME
	      Specify the name of the connection to receive the message.

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

       --system
	      Send to the system message bus.

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

       --type=TYPE
	      Specify "method_call" or "signal" (defaults to "signal").
