The dbus-launch command is used to start a session bus instance of dbus-daemon from a shell script. It would normally be called from a user’s login scripts. Unlike the daemon itself, dbus-launch exits, so backticks or the $() construct can be used to read information from dbus-launch.

How do I use dbus-send in Linux?

Nearly all uses of dbus-send must provide the –dest argument which is the name of a connection on the bus to send the message to.
What happens if dbus-send is not specified?
If neither is specified, dbus-send sends to the session bus. Nearly all uses of dbus-send 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. The object path and the name of the message to send must always be specified.
