Want to find files with exactly the right size

Have you ever come across some files in your application that just appear to be generated by err…..a generator and actually do nothing. Well I find a couple of javascript files with the same content (and therefore the same size) and wondered if there were any more.

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/

Well fortunately you can use find with a specific option

Robs-MBP:blah rl$ find app/assets/ -size 229c
app/assets//javascripts/some.js.coffee

Excellent, I can ditch that file too then.
