Password with known letters

[outaspace]

Hello everyone, great forum here, I´m Alex and i try to familiarize myself with hashcat!

I have a simpler question. I just can't manage a brute force mask attack with certain letters. So I know 4 characters (A; i; 1; u) of a 10-digit password, but I don't know any order or position. Do you know how I can best implement this?

i tried:
hashcat.exe -a 3 -m 16600 -w 3 hash.txt 10char-1l-1u-1d-1s-compliantAi1u.hcmask

I added $A, $i, $1 and $u to the original Maskfile but hashcat tries all the variations anyway.

Do you know an option how i can handle that correct?

I´m sorry about my english...

Thank you for your support!
