~~~~~~~~~~~~~~~~~~~~~
require 'readline'

module MYCMD

CompletionProc = proc { |input|
   case input
   when /^cd/
     typed = input.sub("cd","")
     typed.strip!
     save = input.sub(/#{typed}\z/,"")
     fragment = File.basename(typed)
     tmp = Dir.entries(File.dirname(typed))
     candidates = tmp.select {|f| f.match(/^#{Regexp.quote(fragment)}/)}
     candidates.map! {|f| save+File.dirname(typed)+"/"+f+"/"}
   end
}
#Readline.completer_word_break_characters=  "\t\n\"\\'`><=;|&{("
Readline.completer_word_break_characters=  "\t"
Readline.completion_append_character = nil
Readline.completion_proc = MYCMD::CompletionProc

loop do
   cmd = Readline.readline
   eval(cmd.chomp)
end

That was what you have expected, or?
