SSH-COPY-ID(1)                                                  SSH-COPY-ID(1)



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 pass-
       word 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 writabil-
       ity (which would otherwise prevent you from logging in, if the remote sshd has StrictModes set in its  configu-
       ration).   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)
