Create SSH key exchange from one host to the other

cat ~/.ssh/ | ssh <remote_host> "xargs --null echo >> ~/.ssh/authorized_keys"
Well its just appending your public key to the remote hosts authorized_keys, but can get messy logging in and out

not everyone has the ssh-copy-id shell script installed on their system, and this snippet is pretty much what it does. xargs could be replaced with cat here.

this is the same: ssh-copy-id -i ~/.ssh_[d|r] user@machine
