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)
