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

SYNOPSIS
       dbus-send [--system | --session | --bus=ADDRESS | --peer=ADDRESS] [--sender=NAME] [--dest=NAME] [--print-reply [=literal]]
                 [--reply-timeout=MSEC] [--type=TYPE] OBJECT_PATH INTERFACE.MEMBER [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 (message 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 | uint16 | 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 member 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 in a human-readable form. It also means the message
           type (--type=) is method_call.

       --print-reply=literal
           Block for a reply to the message sent, and print the body of the reply. If the reply is an object path or a string, it
           is printed literally, with no punctuation, escape characters etc.

       --reply-timeout=MSEC
           Wait for a reply for up to MSEC milliseconds. The default is implementation-defined, typically 25 seconds.

       --system
           Send to the system message bus.

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

       --bus=ADDRESS
           Register on a message bus at ADDRESS, typically a dbus-daemon.

       --peer=ADDRESS
           Send to a non-message-bus D-Bus server at ADDRESS. In this case dbus-send will not call the Hello method.

       --sender=NAME
           Request ownership of name NAME before sending the message. The name will be released when dbus-send exits.

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