Assuming that U're using bash, use double-quotes around the shell
variable; single-quotes escape the dollar-sign ($) for variables.
If U need to mix-and-match single- and double-quotes, adjacent
strings (no intervening whitespace) are automatically concatenated,
so this string:
   sed '1,$ s^8080^'"$Shutdown_Port"'^' ...
should fill the bill.
