Find.find reversed order on MacOSX Snow Leopard
 

Hi all,

I just found out that the following code yields the directory listing in
reverse alphanumerical order on Snow Leopard (10.6.1). This is with the
out-of-the-box ruby install.

require 'find'
Find.find '/Library/Preferences/' do |x| puts x end

On MacOSX 10.5 Leopard, it yielded the listing in either default system
order, or alphanumerical order, I don't remember.

Is it expected behaviour and what can I do to restore the previous one?

thanks
Raphaël

Just tried that on 10.5 and it still gives reverse alphanumerical order.

I understand now that any sort performed on a find() would delay it
until directory traversal is complete.

Thanks for your answers.
