I love tinkering away in scriptcs :) Guessing this has been discussed already.... but here goes anyway!

It would be neat if, when working at the command line, a few shell commands were available. They wouldn't need to be super succinct, even just aliasing static methods from System.IO would be fine for many:

> #ls "C:\\Windows"
[
  "addins",
  "AppCompat",
  "...",

(#ls foo where foo is a defined variable might also work this way).

I'd use this when interactively exploring and testing other scripts and C# code.

There are a few quick cheap-ish wins:

• ls
• pwd
• cd
• rm
• cp
• mv

Some form of cat or commands for reading/writing objects to files with ToString() would top it off.

var x = "Hello";
#write "greeting.txt" x
#read x "greeting.txt"

(We support .csx files in Octopus Deploy to perform system management tasks, so these commands seem like they'd be useful in that context, at least when debugging/prototyping.)
