[redis] How to connect to remote Redis server?

One thing that confused me a little bit with this command is that if redis-cli fails to connect using the passed connection string it will still put you in the redis-cli shell, i.e:

redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> 

You'll then need to exit to get yourself out of the shell. I wasn't paying much attention here and kept passing in new redis-cli commands wondering why the command wasn't using my passed connection string.
