B While they have similar purposes, B<-i> and B<-I> have very different syntax and semantics. B<-i> can only be specified once and takes a perl compatible regular expression which is matched against the full relative path of each file. B<-I> can specified multiple times and takes a filename pattern with shell wildcards. The pattern is applied to the full relative path but also to each part of the path individually. The exact semantic of tar's --exclude option is somewhat complicated, see http://www.gnu.org/software/tar/manual/tar.html#wildcards for a full documentation.
