One note about the above, you are useing the '/bin/sh' instead of '/bin/sh5'.
The SunOS 4.0 might be useing the 'sh' that conforms to the SYSTEM V. Where
the above above 'sh5' conforms to SYSTEM V Release 2 (according to the man
page here under ULTRIX 3.0). I have not look through the man page for
'/bin/sh', but I don't think it says that it is a 100% compatible to ATT sh.

I think the '/bin/sh' comes from BSD.

Hope this helps some.
