I don't like using the piping because it doesn't have much ways to
deal with duplicates which show up quite a bit. It also breaks down on
the simple problem that if your computer reboots, crashes etc you have
no idea where you were in the wordlists. I found that over most
wordsets I got a lot of duplicates (where 60% of one set of
dictionaries were the same words in different groups.)
Combining them and using jtr's unique worked a lot better and then
allowed suspended/crashed/etc jtr's to be restarted
so here is how I figure out what ones are dupes and put them at the
top of the list because they usually are passwords that are
ubiquitous(sp?). This works for lots of small dictionaries (say less
than 2 GB of stuff).
cat wordlists/* | sort | uniq -c | sort -bnr | cut -c 9- | unique big-wordlist
For very large ones I just make due with a sort -o big-wordlist -S <as
much memory as I can spare> wordlist/* and then use
john --wordlist=big-wordlist
