Hi ..

In one of my apps, I am doing something like

 def clean
   f = `rm -f #{@datadir}/*.raw`
 end

I could, just as easily do

 def clean
   Dir["#{@datadir}/*.raw"].each do |f| File.delete(f) end
 end

Besides the portability aspect  (does 'rm' exist on the box?), is one to be 
preferred to the other?

Regards,
