dbus-run-session - start a process as a new D-Bus session
dbus-run-session [--config-file FILENAME] [--dbus-daemon BINARY] [--] PROGRAM [ARGUMENTS...]
dbus-run-session is used to start a session bus instance of dbus-daemon from a shell script, and start a specified program in that session. The dbus-daemon will run for as long as the program does, after which it will terminate.
One use is to run a shell with its own dbus-daemon in a text-mode or SSH session, and have the dbus-daemon terminate automatically on leaving the sub-shell, like this:
dbus-run-session -- bash
or to replace the login shell altogether, by combining dbus-run-session with the exec builtin:
exec dbus-run-session -- bash
Another use is to run regression tests and similar things in an isolated D-Bus session, to avoid either interfering with the "real" D-Bus session or relying on there already being a D-Bus session active, for instance:
dbus-run-session -- make check
or (in automake(1)):
AM_TESTS_ENVIRONMENT = export MY_DEBUG=all;
LOG_COMPILER = dbus-run-session
AM_LOG_FLAGS = --
--config-file=FILENAME, --config-file FILENAME
--dbus-daemon=BINARY, --dbus-daemon BINARY
dbus-run-session exits with the exit status of PROGRAM, 0 if the --help or --version options were used, 127 on an error within dbus-run-session itself, or 128+n if the PROGRAM was killed by signal n.
PATH is searched to find PROGRAM, and (if the --dbus-daemon option is not used or its argument does not contain a / character) to find dbus-daemon.
The session bus' address is made available to PROGRAM in the environment variable DBUS_SESSION_BUS_ADDRESS.
The variables DBUS_SESSION_BUS_PID, DBUS_SESSION_BUS_WINDOWID, DBUS_STARTER_BUS_TYPE and DBUS_STARTER_ADDRESS are removed from the environment, if present.
