qdbus:tldr:82705
The command "qdbus" is a command-line tool that allows you to interact with D-Bus services on your system. D-Bus is a message bus system that enables applications to communicate with each other.
"${service_name}" is a placeholder that should be replaced with the actual name of the D-Bus service you want to interact with. D-Bus services are registered on your system and have unique names.
By running the "qdbus" command with the appropriate service name, you can list the available methods, properties, and signals of the given D-Bus service. This can help you understand how to interact with and control the service programmatically.
For example, if you have a service named "com.myapp.service", running the command "qdbus com.myapp.service" would provide you with a list of available interfaces and their associated methods, properties, and signals. You can then use this information to interact with the service as needed.
