I used a brute force perl script recently, for getting into an old zip file, and it started me thinking about word list generation.

Now I know bash scripting isn't a very good way to brute force or generate word lists because it would be slow. But the reason I want to get one working is more as a bash programming exercise really, and because when I get something stuck in my head....

So, my question is simply how I would go about creating a script which would generate words (lets just output each one on its own line for now) in a progressive fashion (a, b, c..... aa, ab, ac....) from a list of specified characters.

Thanks

i can do it in perl:

perl -e 'map {print "$_ "} ('a'..'zz');'

I don't think there's anything as concise as that in bash, the nearest equivalent would be:

echo {a..z}; echo {a..z}{a..z} #etc...
