mixalpha-mask attack

[spiritraider]

Code:

hashcat -m 2200 -a 3 abc.hc22000 -1 abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ  ?l?l?l?l?l?l?l?l

Is this syntax correct to crack a password created as mixalpha with a length of 8 characters (without numbers and symbols)? 

for example: YsFdxjHv
                     sdhSUiPg
                     kkJSAsCX
