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 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 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 con- tainers (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. --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"). AUTHOR

dbus-send - Send a message to a message bus SYNOPSIS
dbus-send [--system | --session] [--dest=name] [--help] [--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. There are two standard message buses: o systemwide message bus - Disabled and not supported on Solaris, but installed on many systems as the "messagebus" init service. o per-user-login-session message bus - Enabled and supported on Solaris, and 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 speci- fied, 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. See http://www.freedesktop.org/software/dbus/ for more information. OPTIONS
The following options are supported: --dest=name Specify the name of the connection to receive the message. --help Show help information on standard output and exit. --print-reply Block for a reply to the message sent, and print any reply received. --session Send to the session message bus (this is the default). --system Send to the system message bus. The system bus is disabled and unsupported on Solaris. --type=type Specify "method_call" or "signal" (defaults to "signal"). OPERANDS
The following operands are supported: destination_object_path The object path of the message to send must always be specified. message_name The name of the message to send must always be specified. contents Following arguments, if any, are the message contents (message arguments). These are given as a type name, a colon, and then the value of the argument. The possible type names are: string, int32, uint32, double, byte, bool- ean. (D-Bus supports more types than these, but dbus-send currently does not.) EXAMPLES
Example 1: How to use dbus-send with a sh-compatible shell to start the per-session bus daemon example% dbus-send --dest='org.freedesktop.ExampleName /org/freedesktop/sample/object/name org.freedesktop.ExampleInterface.ExampleMethod int32:47 string:'hello world' double:65.32 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.
