Subject: Re: What is the best way to edit a file to eliminate a line

Ok, slightly more elegant...

class File
   def self.modify filename
     if block_given?
       data = IO.read filename
       begin
         file = File.open filename, 'w'
         yield file, data
       rescue Exception => ex
         file.open( filename, 'w' ){|file| file.write data }
       ensure
         file.close unless file.closed?
       end
     end
   end
end


File.modify( 'stuff.txt' ) do |writable_file, original_file_contents|
   writable_file.write original_file_contents.gsub /foo(\n|$)/, ''
end

Hope this works better...
