NAME

6       dbus-send - Send a message to a message bus
7

SYNOPSIS

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

DESCRIPTION

14       The dbus-send command is used to send a message to a D-Bus message bus.
15       See   http://www.freedesktop.org/software/dbus/  for  more  information
16       about the big picture.
17
18
19       There are two well-known message  buses:  the  systemwide  message  bus
20       (installed  on  many  systems as the "messagebus" service) and the per-
21       user-login-session message bus (started each time a user logs in).  The
22       --system and --session options direct dbus-send to send messages to the
23       system or session buses respectively.  If neither is  specified,  dbus-
24       send sends to the session bus.
25
26
27       Nearly  all uses of dbus-send must provide the --dest argument which is
28       the name of a connection on the bus to send the message to.  If  --dest
29       is omitted, no destination is set.
30
31
32       The  object  path  and  the  name of the message to send must always be
33       specified. Following arguments, if any, are the message contents  (mes‐
34       sage arguments).  These are given as a type name, a colon, and then the
35       value of the argument. The possible  type  names  are:  string,  int32,
36       uint32,  double, byte, boolean.  (D-Bus supports more types than these,
37       but dbus-send currently does not.)
38
39
40       Here is an example invocation:
41
42         dbus-send --dest='org.freedesktop.ExampleName            \
43                   /org/freedesktop/sample/object/name              \
44                   org.freedesktop.ExampleInterface.ExampleMethod   \
45                   int32:47 string:'hello world' double:65.32
46
47
48       Note that the interface is separated from a method or signal name by  a
49       dot, though in the actual protocol the interface and the interface mem‐
50       ber are separate fields.

OPTIONS

54       The following options are supported:
55
56       --dest=NAME
57              Specify the name of the connection to receive the message.
58
59       --print-reply
60              Block for a reply to the  message  sent,  and  print  any  reply
61              received.
62
63       --system
64              Send to the system message bus.
65
66       --session
