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

OPTIONS¶
The following options are supported: --dest=NAMESpecify 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. It also means the message type (
--type=) is method_call.
--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.)
--address=ADDRESS
Send to ADDRESS.
--type=TYPE
Specify method_call or signal (defaults to
" signal").
