I'm home and not near any documentation, but I think that your use
of 'g' here with ".,$" is improper. Global HERE means EVERY LINE, so the
range probably gets ignored. You should simply do
:.,$ s/pattern/pattern2/g
In this case the TRAILING 'g' says to make the substitution
more than once per line if necessary, but the specified range will be
honored. I think your second illustration (which I've cleverly
deleted from this file before talking about it, so this may be
nonsense) is correct: it will check ALL lines - not a range - for
PATTERN and if it finds it will make one substitution only in
such lines. I'll not suggest you RTFM, because that is precisely
what's wrong with vi: reading most of its documentation is about like
having root canal done - rectally. Good luck.
