Apparently, I have run into an area of some controversy (or at least
some disagreement)
On my Solaris 10 box,
ksh thinks that the expected output should be smith::0.0
sh -> smith:0.0
(an old version of bash) -> smith: 0.0
dtksh-> smith: 0.0
I don't think this will get solved anytime soon. :) Thanks for your
help. We have a workaround.
