Assistance with Unique Rule

[Snoopy]

use delete rule and you can have more than one rule per line
you can use --stdoud to see how rules actually work
using your dict.txt and
r.txt
D0 D0
hashcat -a 0 dict.txt r.txt
->
abama
aska
izona
kansas

as you can see, just combine rules in a line, D0 D0 means delete postion 0 from pw = new pw -> delete postion 0 from new pw (the rules are applied in line) so D0 D0 actually translates to delete the first 2 positions
if you switch to D0 D1 in r.txt it results in

lbama
lska
rzona
ransas

explanation for Alabama
delete postion 0 from Alabama -> labama
delete postion 1 from labama -> lbama

hope this helps
