You will never, ever, under any circumstances, be able to pass variable
assignments to this.

This API is only suitable for chain-loading external commands, as in:

sh runner.sh mydb start password='apple sauce'

It's great for that.  But you can't give it anything that the shell
has to process, like variable assignments, if/then/fi compound commands,
redirections, etc.

P.S. put a shebang in your script already.

#!/bin/sh
exec "$@"

Then you can run it directly without needing to type "sh " every time.
