How do I pronounce "vi" , or "!", or "/*", or ...? You can start a very long and pointless discussion by wondering about this topic on the net. Some people say "vye", some say "vee-eye" (the vi manual suggests this) and some Roman numerologists say "six". How you pronounce "vi" has nothing to do with whether or not you are a true Unix wizard.
Similarly, you'll find that some people pronounce "char" as "care", and that there are lots of ways to say "#" or "/*" or "!" or "tty" or "/etc". No one pronunciation is correct - enjoy the regional dialects and accents.
