[Konsole-devel] Controlling konsole with dbus

Indeed.  It looks as though the new window will try to register an
interface at /Konsole and then fail
since one already exists.

If your script is running from a terminal then running konsole will
start a new process with one window
which can be accessed via org.kde.konsole-$PROCESS_ID.

The newSession DBus call returns the ID of the tab/session.  You can
then execute commands
using the sendText method of that session.

qdbus org.kde.konsole /Sessions/$sessionId sendText "<command> <new line>"

Freedesktop.org contains information about DBus in general.
You can use qdbusviewer to inspect the interfaces provided by each
application, call
methods and so on.  I'm afraid I don't know of any good documentation
to recommend
on how to do specific things with DBus in KDE.

Robert.
