Commands? 
--help is your friend if you have never used cpuminer. You'll need to use the cryptonight algorithm.
I have used cpuminer before but not with cryptonight... how about an example in OP?
If you've used cpuminer before, then what I supplied in my post should have been enough, I think - but never mind, I'll give you a full command:
Code:
minerd -a cryptonight -o moneropool.org:80 -O 43jtN2e88d4ayn7gxsLwB94fmYzLuXymuGdJxotnvYsCaK3UuhvQRNgKrZUD4i5kxTRtpz49FrB1e2KYiXu4TNyEEGUwu9E:x -t 4 --no-longpoll
