I'm trying to find a regex i.e. as used by GREP to find all words in "badugly" with each letter used only once and all are 7-letter words i.e. they are all anagrams; perhaps it's my age (I hit 70 soon, after decades in Unix) but I cannot seem to find a way to restrict the count i.e. each letter used only once, but in any order. I'll guess that it involves some obscure use of "{}*\" etc, which I've never really grokked... Ta muchly. -- Dave
