“In order to communicate with running applications on
the D-Bus, we need a front end CLI application, or we could use a
language binding (say python bindings). However, we will choose a
CLI application. It is possible to use “dbus-launch”, or the
“qdbus” command part of Qt4. I will be using qdbus since it
demonstrates the point and is faster to use. So, let’s launch
qdbus, and list the running communications buses.”
