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 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.
