Description:

 """ Runs a command in background. No output is retrieved. Useful for running GUI applications that would block click events. :param command: A string or a list of strings containing the name and arguments of the program. :param detach: If set to `True` the program will be executed using the `i3-msg` command. As a result the program is executed independent of i3pystatus as a child of i3 process. Because of how i3-msg parses its arguments the type of `command` is limited to string in this mode. """
