problem with user:hash

hey, when I have just hashes in hash.txt file I do sth like that :


-m 0 -a 0 -o C:/cracked.txt C:hash.txt C/wordlist

but when I want to put format email:hash and I want to add --username, where should I put this "--username" ? (where exactly in " -m 0 -a 0 -o C:/cracked.txt C:hash.txt C/wordlist ") ?
