Make a public key from just your private key

So I was on my main system which only has my private keys for some remote servers….and I’m lazy soo, since I needed to deploy a new server, I just used the following command to make a public key from my already existing private key…

ssh-keygen -f ~/.ssh/id_rsa -y > ~/.ssh/id_rsa.pub

NOTE: You can only go private > public, not the other way around.
