i would customize irb.  for example


   harp:~ > cat a.rb
   def ls g = '*'
     Dir.glob(g){|entry| puts entry}
   end

   def cd d = File.expand_path('~')
     Dir.chdir d
   end


   irb:~ > irb -r ./a.rb
   irb(main):001:0> ls 'skype*'
   skype-1.2.0.18
   skype-1.3.0.53
   skype_staticQT-1.3.0.53-generic.tar.bz2
   => nil


   irb(main):002:0> cd '/tmp'
   => 0
