GetoptLong::each as well as GetoptLong::get consume the options. After
the first opts.each{..} your opts are emtpy.

The docs don't mention that, I think. I also had those troubles when I
used opts.get == nil to check if no options were given.

Perhaps you should have a look at the optparse module in the stdlib.

Insert a "p a" in the second opts.each block and see what happens. :-)

Kind regards
