Valentine's Day. ssh-copy-id

This lovely Valentine’s, I learned about a cool command for automating ssh logins to another computer.

ssh-copy-id sets up the ssh keypair exchange for you automatically by just running it against your username@host-ip like so:

ssh-copy-id root@123.456.789

Then, it’ll ask you for your password, and voila! You should now have ssh setup between your computer and the host such that the next time you run ssh root@123.456.789 it will just auto-log you in, no passwords required!
