[Message part 1 (text/plain, inline)]

Single quote behave normally but double quote is replacing the "$$"
character with pid of open shell and "$<some text >" would not print
anything as if it acting as a comment. Basically the problem is that double
is parsing some of special character which it should not.
In the attachment you would see hash having "$" in between then and is
being parsed as mentioned above and hence does not write anything in file.
Thanks and Regards.

That is normal shell behaviour. $y expands to the value of variable y, 
$j9T of variable j9T etc.
Try setting some variables before to verify. And use single quote for 
every string that should not be expanded.
