Editing Files

Not having the ability to edit files from a Terminal using vi will make using a remote server substantially more difficult. Type vimtutor to start a tutorial on using the vim editor (a modern vi clone). This tutorial runs in the editor and covers the essentials. Learn at least the basics of command/edit modes and saving files before leaving the tutorial.

It is understandable if you wish to use a more familiar editor for writing scripts. See Mac-Setup for how to directly access files on the server from your Mac.
