Prepend character set to list

[TheAviator]

hashcat -a 3 wordlist.txt ?a --stdout > newwordlist.txt

?a = ?l?u?d?s

Thanks champ, but are you sure???
Because this doesnt work on windows or k@li?
i get error

?a unsupported file type

But even if it did, i think it would append (add to end) not 'prepend', thats why i was messing with the ?^d
