This script will scan for a specific mask on directories and print out the result:
#!/usr/bin/env ruby
require 'find'
require 'etc'
# http://permissions-calculator.org/
MASK = 0002
Find.find(ARGV[0] || "./") do |path|
if FileTest.directory?(path)
s = File::Stat.new(path)
if (s.mode & MASK) != 0
puts "#{s.mode.to_s(8)} #{Etc.getpwuid(s.uid).name} #{Etc.getgrgid(s.gid).name}: #{path}"
end
end
end
