cracking sha256 with a 2 digit salt

Hey everyone, I'm very new hashcat and cracking in general. I'm currently trying to learn, but am very very very clueless! Having said that, I have ~400k hashes and I would like to crack as many of them as possible. All I know is that it's sha256 with prepended with a 2 digit salt. I'm very confused syntactically as to how to proceed.

when I try


I get line length exceptions. I'm not really sure how I'm supposed to specify what the salt is, or how to try all 100 salt possibilities. Any and all advice is appreciated!


Thanks!
