          ^^^^^^^^ this bit is more reliable for sh on Solaris (real Bourne shell)

you can install the shells/heirloom-sh package from ports (it installs as `jsh') for `compatibility' testing, I believe Bourne shell is typically considered the most
restrictive of the POSIX shells (although i believe it is not technically compliant with IEEE Std 1003.2 (``POSIX.2'') ... neither is FreeBSD shell, although it is closer).
