Can hybrid attack work with rules?

[SopalajoArrierez]

If you want to "split" the rules, there is also another interesting feature called multi-rules: see https://hashcat.net/wiki/doku.php?id=rul...ulti-rules .
Basically, you can do -r append_num.rule -r duplicate.rule

Fine! That is the one I was searching for.
When reading the docs, I thought multirules where sequential (attack the hash by using append_num.rule, then attack the hash by using duplicate.rul, not combined).
It makes more sense now.
Thanks you all for explaining.
