My suggestion is to use whitespace, i.e., indentation and blank lines, to clarify what parts of your post are questions, code, background information, data, etc.. With it all run together I'd need to copy and reformat to make any sense of it. I started to do that, but didn't get far. I'm all for bash scripting, but it can get pretty obtuse. When I get that sort of error it's back to the manpage, try some different forms, just mess with it generally until it works. For the particular error, create a much simplified script with only the [[ ... ]] construct, and then see what's needed to make it work. It's probably something simple -- maybe escape the newline after 'then'? Perl, python, ruby, awk, tcl, etc., etc., are all available and in many cases can be clearer and easier to use when it comes to scripting. Good luck!
