The first executable line is redundant, because when you redirect the output of the env to ~/.Xdbus, that will create it, meaning that the chmod line can be moved down one, so that the file exists when the command is executed. I'm not saying that you have to do it this way, but it just looks cleaner the other way, at least to me. YMMV, and it's your system.
