Copying Files with SSH
| scp source user@host:destination | Copies 'source' to 'host' at 'destination'. |
|
| scp user@host:source destination | Copies 'source' from 'host' to local 'destination'. |

| scp -r dir user@host:destination | Copies the entire directory 'dir' to 'host' at 'destination'. |
SSH Config File
You can create a config file for ssh as ~/.ssh/config to simplify your ssh commands:
Host myhost HostName host.com User username Port 2222 IdentityFile ~/.ssh/key.pem
Now you can just use 'ssh myhost' instead of the full command.
