.SH NAME
dbus-send \- Send a message to a message bus
.SH SYNOPSIS
.PP
.B dbus-send
[\-\-system | \-\-session] [\-\-dest=NAME] [\-\-print-reply]
[\-\-type=TYPE] <destination object path> <message name> [contents ...]
.SH DESCRIPTION
The \fIdbus-send\fP 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.
.PP
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 \fIdbus-send\fP to send
messages to the system or session buses respectively. If neither is
specified, \fIdbus-send\fP sends to the session bus.
.PP
Nearly all uses of \fIdbus-send\fP 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.
.PP
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 a type name, a colon, and
then the value of the argument. The possible type names are: string,
int32, uint32, double, byte, boolean. (D-Bus supports more types than
these, but \fIdbus-send\fP currently does not.)
.PP
Here is an example invocation:
.nf
dbus-send \-\-dest='org.freedesktop.ExampleName \\
/org/freedesktop/sample/object/name \\
org.freedesktop.ExampleInterface.ExampleMethod \\
int32:47 string:'hello world' double:65.32
.fi
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.
.SH OPTIONS
The following options are supported:
.TP
.I "--dest=NAME"
Specify the name of the connection to receive the message.
.TP
.I "--print-reply"
Block for a reply to the message sent, and print any reply received.
.TP
.I "--system"
Send to the system message bus.
.TP
.I "--session"
Send to the session message bus. (This is the default.)
.TP
.I "--type=TYPE"
Specify "method_call" or "signal" (defaults to "signal").
