See\nhttp://www.freedesktop.org/software/dbus/ for more information about the big picture.\n\nThere are two well-known message buses: the systemwide message bus (installed on many systems\nas the \"messagebus\" service) and the per-user-login-session message bus (started each time a\nuser logs in). The --system and --session options direct dbus-send to send messages to the\nsystem or session buses respectively. If neither is specified, dbus-send sends to the session\nbus.\n\nNearly all uses of dbus-send must provide the --dest argument which is the name of a\nconnection on the bus to send the message to. If --dest is omitted, no destination is set.\n\nThe object path and the name of the message to send must always be specified. Following\narguments, if any, are the message contents (message arguments). These are given as\ntype-specified values and may include containers (arrays, dicts, and variants) as described\nbelow.\n\n ::= | [ | ...]\n ::= :\n ::= | | \n ::= array::[,...]\n ::= dict:::,[,,...]\n ::= variant::\n ::= string | int16 | uint16 | int32 | uint32 | int64 | uint64 | double | byte | boolean | objpath\n\nD-Bus supports more types than these, but dbus-send currently does not. Also, dbus-send does\nnot permit empty containers or nested containers (e.g. arrays of variants).\n\nHere is an example invocation:\n\n\ndbus-send --dest=org.freedesktop.ExampleName \\\n/org/freedesktop/sample/object/name \\\norg.freedesktop.ExampleInterface.ExampleMethod \\\nint32:47 string:'hello world' double:65.32 \\\narray:string:\"1st item\",\"next item\",\"last item\" \\\ndict:string:int32:\"one\",1,\"two\",2,\"three\",3 \\\nvariant:int32:-8 \\\nobjpath:/org/freedesktop/sample/object/name\n\n\nNote that the interface is separated from a method or signal name by a dot, though in the\nactual protocol the interface and the interface member are separate fields.\n", "subsections": [] }, "OPTIONS": { "content": "The following options are supported:\n\n--dest=NAME\nSpecify the name of the connection to receive the message.\n", "subsections": [ { "name": "--print-reply", "content": "Block for a reply to the message sent, and print any reply received in a human-readable\nform.
