dbus-launch 命令

常用示例

说明

dbus-launch starts a session instance of the D-Bus message bus daemon and provides the connection address to client applications. It's typically used to ensure a D-Bus session is available for desktop applications. When invoked without arguments, it prints environment variables (DBUS_SESSION_BUS_ADDRESS and DBUS_SESSION_BUS_PID) that clients need to connect. With shell syntax options, the output can be directly evaluated to set these variables. When a program is specified, dbus-launch starts the D-Bus daemon, sets up the environment, and then executes the program. The --exit-with-session flag ensures the daemon terminates when the program exits.
