NAME
       ssh-copy-id - install your public key in a remote machine's authorized_keys

SYNOPSIS
       ssh-copy-id [-i [identity_file]] [user@]machine

DESCRIPTION
       ssh-copy-id  is  a  script  that  uses  ssh  to log into a remote machine (presumably using a login password, so password
       authentication should be enabled, unless you've done some clever use of multiple identities)

       It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability
       (which would otherwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration).

       If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are
       any keys in your ssh-agent.  Otherwise, if this:

             ssh-add -L

       provides any output, it uses that in preference to the identity file.

       If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file.  Once it has
       one  or  more fingerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine
       (creating the file, and directory, if necessary)
