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

$myString =~ s/^\s*(.*?)\s*$/$1/;

This will trim whitespace from both sides.

from just the right:

$myString =~ s/\s*$//;
