how to create a rule for at least one number and lower char

[paranoyakx]

please forgive my lack of explanation. I am quite new at hashcat and might use terminology wrong. basically what I need is, to crack a hash which contains both lower case characters and numbers. so I know that at least one character or number exists so if I define my mask as this: " -1 ?l?1 " it will generate passwords starting from aaaaaa to 999999 right? but I don't want to test aaaaaa or abghre because there must be at least one number in it. likewise I don't want hashcat generate 1111111 either because there must be at least one character. so is this possible to define using masks (or rules or any other option) ?

my current execute command:
hashcat -a 3 -m 22100 -1 ?l?1 ?1?1?1?1?1 hash.txt

thanks.
