REGEX: $n++ if ($small_string=~ /.*grand.*/);

[polka4ever]

I am pretty new to regular expressions. I have a book and I am reading fervently, but unable to get this to work. I'd like to increment n anytime my variable has the value 'grand' in it.

First question: Is this case sensitive? If so - how do I make it NOT case sensitive?

I am trying to match up with the city: Grand Rapids - so it seems like it should be incrementing for:
$small_string=~ /.*grand.*/

What am I not getting here?

If you want to match 'Grand Rapids' why are you only using grand?

my $string = 'The name of this famous city is Grand Rapids. It is a grand city full of many wonderful surprises. Come to Grand Rapids whenever you can, we will show you a grand time!';
my $n = $string =~ s/(Grand Rapids)/$1/ig;
print $n;

The 'i' makes it case insensitive and the 'g' forces perl to search the entire string. You can also use the map function for this purpose:

my $n = map {m/Grand Rapids/ig} $string;

but I am not sure if there is any advantage or disadvantge using one method over the other.
