Your client software will first try to establish a non-interactive session on the server. It will fail with an error if the non-interactive portion of your shell's startup prints anything.

It's safe to place such modifications in ~/.bash_profile which only configures interactive logins. |

This process is more involved in that one must create the directory remotely first and then transfer the contents from one to the other – wildcards are helpful for this. |
