DESCRIPTION
       ssh-copy-id is a script that uses ssh to log into a remote machine  and
       append    the    indicated    identity    file    to   that   machine's
       ~/.ssh/authorized_keys file.

       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.)

NOTES
       This program does not modify the permissions of any pre-existing  files
       or  directories.  Therefore,  if the remote sshd has StrictModes set in
       its  configuration,  then  the  user's   home,   ~/.ssh   folder,   and
       ~/.ssh/authorized_keys file may need to have group writability disabled
       manually, e.g. via

             chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys

       on the remote machine.
