Having a bunch of files with weird encoding you need to replace something in ?
Pru to the rescue!
(because replacing with ruby-regex or sed leads to encoding exceptions)


find test -name "*" | pru 'return unless File.file?(self); c = File.read(self); s = "SEARCH"; r = "REPLACE"; while x = c.index(s) do; c.slice!(x,s.size); c.insert(x, r); end; File.write(self, c)'


Normal ruby:

String.class_eval do
  def string_sub(s,r)
    while x = index(s) do
      slice!(x,s.size)
      insert(x, r)
    end
    self
  end
end
