Given a SHA512 hash, a salt, and username I am trying to crack the hash using hashcat. Every example I've found used a hashfile as input, is there way to provide salt and hash via commandline without the need to create a hashfile?

Here is an example what I am trying to crack:

    Hash: 6ce9a7c73ebf0c04db026fda907210e7367f6d72225f78399a4a3fc9bfd0cce9
    Salt: a3424259-9534-486a-bfe9-6a2b39aa70e5
