Limiting the consecutive occurrence

[Hash-IT]

you are very correct Hash-IT. It is the pattern of the sequence what you are interested in. Not the content.
crunch 8 8 abcdef | "filter" would give similar result as
crunch 8 8 zbcdef | "filter" but the all the 'a' is swapped with the 'z'

Yes I think that is it, thanks for the confirmation.

So chaps, M@LIK, Pixel and of course ntk, that's all we need to do !! I assume you can each generate your own "primary pattern" and there is no need to share them between ourselves ? If any of you need help post here and I will do what I can.

Good grief this will save a massive amount of disk space !

Sooo.... the next step is to make our substitution rule file, I think it will be simple enough so I will try to do it on my own for us all if you like. I would appreciate it if you would all give it a look over to make sure I have worked it out correctly. Not you though M@LIK, you have revising to do for your exams !!!

Give me some time and I will post it here....probably !
