ssh - Command to send public key to remote host

Question

I remember there is a command to send public key to the remote host that I want. I want to use that feature to send one of my public keys to the other host. How can I do that?

Answer 1

You are looking for ssh-copy-id. All this command does is create .ssh and .ssh/authorized_keys and set their permissions appropriately if they don't exist. Then it appends your public key to the end of .ssh/authorized_keys.
