.SH NAME
dbus-send \- Send a message to a message bus
.SH SYNOPSIS
.PP
.B dbus-send
[\-\-system | \-\-session] [\-\-dest=SERVICE] [\-\-print-reply] <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 service on the bus to send the message to. If
\-\-dest is omitted, a default service name of
"org.freedesktop.DBus.Broadcast" is used.  

.PP
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.ExampleService'     \\
            org.freedesktop.ExampleMessage              \\
            int32:47 string:'hello world' double:65.32

.fi

.SH OPTIONS
