Right then, vi. “Oh no! vi! That’s command based, can’t use that!” Oh come on, it’s not that difficult! Really… First, I shall explain a little about vi. vi (now mostly vim) is one of the oldest text editors for *nix. It can be found on many systems, both UNIX and Linux, and is usually the default editor. vim (VI iMproved) is beginning to take over from the older vi, but essentially, they function the same way.
