Subject: Nuby: 'importing shell script variables' eval/proc/binding

Greetings,
   I'm pretty sure eval/proc/binding needs/can be used to solve my 
problem, but I'm having difficulty grasping those concepts.

Given a series of shell scripts (bourne based) containing code such as

FIRST=Dany
LAST='Cayouette'
FULLNAME="$FIRST $LAST"
UID="danyc ($FULLNAME)"

I would like to 'import' those value into a Ruby Hash such that the end 
result is something like
{"LAST"=>"Cayouette", "UID"=>"danyc (Dany Cayouette)", "FULLNAME"=>"Dany 
Cayouette", "FIRST"=>"Dany"}

So far I have
class Hash
   def shparse (file)
     File.open(file, "r") do  |f|
       while line = f.gets
         next unless line =~ /^\s*(\w+)=(.*)$/
         k = $1
         v = $2
         self[k] = v
       end
     end
    p self
    self
   end
end


Which gives me some of the basics, but not the 'expansion' of $VARS.

Any help/input appreciated.
Dany
