Not yet, because I haven't started :)

But I'll follow your advice and post on demand...
As I said I don't really know ruby. I read quite a lot already but haven't 
got my hands dirty yet with some real stuff, so I'm using this as an excuse 
so do something real.
Last time I found motivation in programming something arbitrary just to 
learn a new language was about 20 years ago, but this would be inmediately 
useful, so should be fun.

I'll try to identify patterns and post here my proposed counterparts.
For instance, I gather so far that FileUtils would provide most file/dir 
handling.
My probably next step is to find out how to port typical grep/sed commands 
(their typical usage, not all of it)

Fortuntely the scripts I need to port are not that overly-clever, so I don't 
unticipate much trouble.
