8char hash ?l?d

[silentj]

Hey all, I am new to pentesting in general and also hashcat. I am wondering if this would be the correct command to try and find a password where I know it's 8 characters long, and contains lowercase a-z and 1-9. no way of knowing which one is a number and which one is a letter.

example of possible pass: wa5kz73 4j9z2k4x atpz32s9 etc

here is the command I'm running: hashcat -m 2500 1.hccapx -w 4 -a 3 -1 ?l?d ?1?1?1?1?1?1?1?1

is this correct? is there a better way to accomplish cracking this hash?

thanks.
