a page of more webpages from Texas it includes a vi tutorial
a site from New Mexico focussing on the basic vocabulary
a site from Florida focussing on Unix's features (like redirection)
another site, from Idaho, focussing on Unix's features
vi is my personal fav for text editing. It's especially good for program writing/editing (just hit the "%" character several times in the command mode while editing a program to see why). A search of vi tutorials on the web will invariably find sites devoted to vi haters. So, I looked for a few ones that were serious....
very quick, to the point, and short
this one has a link to more tutorials
For tutorials on other text editors, a web search on, say "emacs tutorial" will likely turn up good stuff
If you ever need to contact me for any reason, the best by far is email.
