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
       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 | 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                                 \
                   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").
