Just a quick hack without command line processing.

dir = ...
name_regexp = ...  # may be null
content_regexp = ...  # may be null

require 'find'

Find.find dir do |file|
  path, base = File.split file
  next if name_regexp && name_regexp !~ base or
    content_regexp && context_regexp !~ File.read(file)
  puts file
end

For command line processing I'd use OptionParser.

Kind regards
