How do I remove white space in a Perl string?

Question

If I declared a variable $myString with the value \'3 \' (notice the white space). Is there any function to remove the white space for the return v

Answer 1

If you are willing to use a CPAN module then String::Util, or the somewhat more economical Text::Trim would be possible choices.

Trimming strings is one of those bike sheds that everyone likes to build! See the short perlmaven tutorial by @szabgab for a small sample of TIMTOWDI fun.
