sha512 find password with known pass and salt

[Tiralo33]

Hello,

i tried to find passwords with known pass, salt and i know that it uses sha512
I think i need to use the hash type -m 1710 sha512($pass.$salt) but i'm just guessing
As far as I understand, I have to create two files, one for the pass and one for the salt part but i'm not sure how to run the command.

I've tried following

c:\Temp\hashcat-6.2.6>hashcat.exe -m 1710 hashes\word.txt hashes\solve.txt
hashcat (v6.2.6) starting

Thank you
