Hybrid attack syntax

What's wrong with these commands? Nothing is getting appended or prepended to the wordlist.

./oclHashcat-plus64.bin -m 2500 Reagan.hccap rockyou.txt $d$d$d$d

./oclHashcat-plus64.bin -m 2500 Reagan.hccap $d$d$d$d rockyou.txt

well for one, it's ?d, not $d. normally this would error out, but since your shell is interpreting $d as a string of empty variables, it's like those $d's don't even exist.

you're also missing the attack mode for both of those.

-a 6 rockyou.txt ?d?d?d?d
-a 7 ?d?d?d?d rockyou.txt
