Note that the Bourne shell is not a POSIX shell, making your script portable to Bourne shell would mean downgrading the syntax of your script from the standard POSIX sh language to the common denominator between that and the syntax of the Bourne shell. Not worth the opinion unless you want to be portable to ancient systems (or Solaris 10 and earlier and you don't have the choice to use the standard sh which was in /usr/xpg4/bin there).
