ssh-copy-pub: simpler version of ssh-copy-id for copying employee/contractor public keys to remote server authorized_keys file

ssh-copy-pub

#!/bin/sh
display_usage() {
  echo "This script must be run with at least 2 arguments."
  echo "\nUsage:\n$0 pubKeyFile {ssh arguments}\n"
  echo "Example: ssh-copy-pub john_rsa.pub root@server.example.com\n"
}
if [ $# -lt 2 ]
then
  display_usage
  exit 1
fi

pubKeyFile=$1; shift
cat $pubKeyFile | ssh "$@" 'cat >> .ssh/authorized_keys && echo "Key copied"'

Would like to mkdir -pm 700 .ssh && before the cat, but can't break the pipe....
