You can use various utitlities to search file---eg GREP, SED, AWK

As for the VI question, does the manual (or man page) say anything about this?

You don't need the cat - grep pattern file works.

What do you mean by "proper syntax"? I don't see any syntax mistakes here. For any of these commands, the man page will give you the syntax.

Do you have some kind of reference material? (e.g. the Bash Guide for Beginners)

1. grep string file
2. :?string-to-find (? = search backwards)
