Not good.  The "#!/bin/sh" must be your first line.

Works for me.  For example create a file called "try", make it exectable, with
the contents of:

#!/bin/sh -x
echo hello
ls

When you run it, you'll see:

+ echo hello
hello
+ ls
<ls output>

Those lines that start with the "+" are the traced commands.  If that doesn't
work for you, I'd question whether /bin/sh is really bash.

There is no "-e" option in my man page.  Change the "-e" to "-x".

As Cameron also pointed out, you can do:

#!/bin/sh
set -x
<rest of script>
