Would appreciate assistance with forming correct command structure

[HelpYourBro]

Here is what I have worked up to so far:

./hc -m 11300 -a 3 --increment --increment-min 12 --increment-max 13 litecoin.hash ?a?a?a?a?a?a?a?a?a?a?a?a

note, he said that he strongly believes it is 12 characters but it could be 13
