mdbus2 (1)

mdbus2 [OPTIONS...] [ busname [ objectpath [ method [ params... ] ] ] ]

The mdbus2 command is used to explore and interact with DBus services on your system bus and session bus. Called without any parameters, it will show the available services on the selected bus. Given a service name, it will show the available objects exported by the service. Given a service name and an object path, it will show the exposed methods, signals, and properties of that object.

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 option directs mdbus2 to operate on the system bus rather than the session bus.

mdbus2 has three modes: The introspection mode, the listening mode (-l), and the interactive mode (-i). The interactive mode features readline command completion and history.

The message bus configuration may keep mdbus2 from seeing all messages, especially if you run it as a non-root user.

--show-anonymous

Include unique DBus names (:1.xyz) in the output.

--show-pids

Include PIDs in the output. (Only valid in introspection mode)

--listen

Start in listening mode.

--system

Use the system bus rather than the session bus.

--interactive

Start in interactive mode.

Here is an example of using mdbus2 to listen to all signals on the session bus.

  mdbus2 -s -l
