Case-insensitive when searching

As you know, pattern matching is case-sensitive when performing a search in UNIX ®. However, if you want vi to be case-insensitive, you can use the: set ignorecase command. Use: set noignorecase to restore case sensitivity. You can also use abbreviations (: set ic and: set noic).

If you want to enable case-insensitive search every time you enter a vi session, add the set ignorecase line to the .exrc file in your home directory.
