Perl: function to trim string leading and trailing whitespace

Question

Is there a built-in function to trim leading and trailing whitespace such that trim(\" hello world \") eq \"hello world\"?

Answer 1

For those that are using Text::CSV I found this thread and then noticed within the CSV module that you could strip it out via switch:

$csv = Text::CSV->new({allow_whitespace => 1});

The logic is backwards in that if you want to strip then you set to 1. Go figure. Hope this helps anyone.
