OK so far.

You have not followed the allowed syntax.  You have an argument which
needs quoting, but you have not enclosed it in double-quotes.  Nor have
you escaped the characters within it that need escaping.

I would not even *attempt* to do what you are trying to do here.  Your
life would become enormously simpler if you would just put this shell
script inside a file, and Exec it as a script.

Attempting to in-line a shell script inside an Exec= line is madness.
