Question about vi

How do I do case insensitive search for a regexp ? So I'm looking for commands like
/ or ? but the matching should be case insensitive.

As far as I can see it doesn't have the information I want.But thanks for the effort.

Are you trying to find a regexp in your file based on a search term? If that is the case, then do:

:set ignorecase

This will make searches case insensitive.

The other option is to use:

:set ignorecase smartcase

This will, if your search term includes no uppercase letters, do a case-insensitive search. If there is an uppercase letter, then the search becomes case-sensitive. So, for example:

bob --> bob, Bob, BOb, BOB, etc.
boB --> boB
BoB --> BoB

And so on.


If you mean that you're trying to search through your file with a regular expression (as in, the search term is a regexp), I found a tutorial which may help at:

:set ignorecase was what I was looking for.Thanks a lot.

Come to think of it I have another question: is there a way to do a search
where every character will be interpreted literally ? So for example * will
not mean match 0 or more of something but it will mean a literal *

One way of course is to escape every special character but what I'm looking for
is some option which if set will mean that every character will be interpreted
literally without escaping anything.

Yes there is: you use :set nomagic
I find the name of the option (magic) rather amusing too.

Ok , I have another one.Let's say I'm typing some text where
I plan to use some long word , for example "installation" , a lot.
Is there a way to make it so that by pressing a single button , f1 for
example , the whole word gets printed ?

If you know the answer to this one , even for (x)emacs please share.

By the way , as I found out , instead of writing :set ignorecase you can simply write :set ic
