May I suggest you also talk about the “less” command. I myself use very often, to go up and down in a file, and with search options too. It also has the g and G options to go directly to beginning or end of file.

Also, you might mention the “view” command, the read-only version of vi, which can be very useful to look at a file with all the vi search options, without risk, since you can’t edit it.

Thanks for a great series of articles.
