1) What does emacs have to do with anything?  Run the script from a shell.

2) Your script has no compound commands of any kind.  No functions, no
   loops, no if statements, no case statements, no subshells, no braced
   command groups.  Nothing at all that would indicate the difference
   between -v and -x.

   Try a script with some of the above.
