I'm writing a tool which, among other things, needs to be able to modify files over an SSH connection. However, I don't want to have to invoke CLI tools on the remote server due to security concerns (TL;DR: string escaping is really hard). How can I do this with either (a) the ssh command-line tool (invoked locally) or, (b), the golang.org/x/crypto/ssh/* packages?
EDIT: Sorry, I forgot to mention. I need to be able to do this all within a single session. On some clients, the server being connected to is behind a load balancer, so if I make multiple invocations, I might end up connecting to different servers.
