for d in $(ls $MYDIR/*)
do
	echo "trace:  $d"
done

versus

Dir["#{MYDIR}/*"].each do |d|
	puts "trace:  $d"
end

So, given the difference isn't much, I'd assert the first one is a 
little clearer.  There are a lot of such examples.

I think another aspect of where I'm at is that everybody knows Bash, and 
I did allude to that before.  If you know people are gonna have to hack 
stuff, and your in a business, you try to provide the best environment 
for them to do so.

I can certainly see it being reasonable to do practically everything in 
Ruby, however, and I wouldn't mind doing that if the work environment 
made it a reasonable way to go.
