Hi Monks,

What does "\z" mean in Perl?

I have a question about grep function. For the code below:

my @new_array = grep(/^\s+\d+\s+/, @array, $number);

What's the variable "$number" for? I remember grep only takes two input variables, one is the expression and the other one is an array.

Thanks!
