get a good highlighting editor like vim and you'll see these errors

and you probably meant  "#{ key }*"  not '#{ key }*' since only the former
expands the variable (note double vs single quotes).

btw.  with huge hashes like this it's far easier to maintain an inlined yaml
doc of the hash that ruby source.  for instance, this is long, but quite easy
to read, maintain, and search:


harp:~ > cat a.rb

require 'fileutils'
require 'yaml'

fileshash = YAML.load DATA.read

Dir.chdir 'u:/indexes'

paths = Dir.glob "*.ps"

paths.each do |path|
   filehash.each{|k,v| puts "#{ v }" if File.fnmatch("#{ k }*", "#{ path }") }
end
