    -l            List the hosts and do nothing else.
    -p <port>     Port for the remote SSH service.

DESCRIPTION ^

This script push local ~/.ssh/id_rsa.pub file (i.e. the SSH public key) onto the remote server's ~/.ssh/authorized_keys. It will chmod .ssh to 700 and .ssh/authorized_keys to 640.

If there's no .ssh directory on the remote server, it will try to create one.

Note that the sh/bash shell is assumed on the remote machines.

When no ~/.ssh/id_rsa.pub file found on the local machine, it will invoke ssh-keygen -t rsa automatically.
