I forgot the `s when I copied it over from HP. It works with both `` and $(..)
Yes, because HP-UX's sh is a Posix shell. See man sh-posix to find out about its capabilities.
Therefore, you should rather use the $(...) style if you don't intend to run the script
unmodified on AIX's or SunOS/Solaris' sh.
