[lug] Odd Shell Script Queries

Oh knowledgeable ones, I have a couple shell script queries. First, the
one I believe there might be an answer to.
Is there an easy way to batch-convert filenames from using dots as
separators to underscores *while leaving the final dot*? That is, I
know I can do:
> echo "ibr-.355.3graph.notitle.pdf"| tr '\.' '_'
but now the final "." is an "_". I'm sure I could use Perl or something
to chomp off the last bit, do the translation, and re-concatenate the
end back, but I thought I'd ask if someone here knew a nice way. (If
you're wondering, LaTeX is b0rking on my habit of using dots in
My second script question is a bit more involved. Namely, at my work we
have multiple printer queues. Two are a LaserJet and Color LaserJet,
with the Color one being more expensive. I began to wonder if there was
a script that parsed a PS or PDF file in such a way that only pages with
color are sent to a color printer, while the rest are sent to the mono.
I'm not enough of a PS/PDF guru to know if this is even possible, but
for a large, mainly-text file (say a thesis) with a few color diagrams,
it would be interesting to know if it exists.
Thanks for the help,
