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").
