ssh-copy-id

SSH-COPY-ID(1)						      General Commands Manual						    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 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 oth-
       erwise 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  fin-
       gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
       if necessary)
