NAME

       dbus-send - Send a message to a message bus

SYNOPSIS

       dbus-send  [--system | --session] [--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  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 in a human-readable form.

       --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.)

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