Cracking bcrypt hash using brute force mode

[Justonthis]

The command makes no sense.

Defining any custom charset like --custom-charset1 (or short -1) without using it within the mask doesn't make any sense and is actually quite a common user mistake.

It would make more sense to use

-1 ?l?u?d and then a mask with ?1?1?1?1

BTW: I always try to mention the problems if I find some within user commands, otherwise other users just go ahead and blindly copy-paste (parts of) commands

Thanks a bunch, I have fixed that and it reduced the time considerably.
I was also wondering if you can make a rule to include only a single number for each word or no number at all.
I hope that's possible and isn't so much to ask. Thank you so much for taking the time to help me.
