The ruby version is almost exactly the same as the perl version, only I 
think it is a little more clear:

  ruby -nae 'puts $F[-1]' <FILE>

You'll get nils in the output for blank lines; depending on what you want to 
do, filtering blank lines is probably appropriate, but a little longer:

  ruby -nae 'puts $F[-1] if $F[-1]' <FILE>
