Help with more "complex" passwords

[jeboaa]

you can add a rule into hashcat then still to reject things that don’t match a pattern , further reducing things

I've been searching forums for maybe a week now for this specific question and found nothing but "referring wiki page" replies.  

I've a password, a damn long one, and that password contains - lets say - 123456 numbers that i know. so i want to make a reject policy that each candidate doesnt contain that 123456 should be rejected (or ignored to accelerate the process to be precise - maybe im wandering in the wrong place i dont know). how to write this? wiki says 

Reject not contain  | /X  |  Reject plains which do not contain char X  |  /e

 and since there is no example of it at the page, i just wrote

-j /123456

is this correct? cuz it seems exactly the same in the command prompt if i didnt write that down at all
