<refsect1 id='description'><title>DESCRIPTION</title>
<para>The <command>dbus-send</command> command is used to send a message to a D-Bus message
bus. See <ulink url='http://www.freedesktop.org/software/dbus/'>http://www.freedesktop.org/software/dbus/</ulink> for more 
information about the big picture.</para>


<para>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 <command>dbus-send</command> to send
messages to the system or session buses respectively.  If neither is
specified, <command>dbus-send</command> sends to the session bus.</para>


<para>Nearly all uses of <command>dbus-send</command> 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.</para>


<para>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.</para>

<literallayout remap='.nf'>
&lt;contents&gt;   ::= &lt;item&gt; | &lt;container&gt; [ &lt;item&gt; | &lt;container&gt;...]
&lt;item&gt;       ::= &lt;type&gt;:&lt;value&gt;
&lt;container&gt;  ::= &lt;array&gt; | &lt;dict&gt; | &lt;variant&gt;
&lt;array&gt;      ::= array:&lt;type&gt;:&lt;value&gt;[,&lt;value&gt;...] 
&lt;dict&gt;       ::= dict:&lt;type&gt;:&lt;type&gt;:&lt;key&gt;,&lt;value&gt;[,&lt;key&gt;,&lt;value&gt;...]
&lt;variant&gt;    ::= variant:&lt;type&gt;:&lt;value&gt;
&lt;type&gt;       ::= string | int16 | uint 16 | int32 | uint32 | int64 | uint64 | double | byte | boolean | objpath
</literallayout> <!-- .fi -->

<para>D-Bus supports more types than these, but <command>dbus-send</command> currently
does not.  Also, <command>dbus-send</command> does not permit empty containers
or nested containers (e.g. arrays of variants).</para>


<para>Here is an example invocation:</para>
<literallayout remap='.nf'>

  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 

</literallayout> <!-- .fi -->

<para>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.</para>
