       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  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                                 \

       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.

       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

              Send to the system message bus.

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

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