There's probably a module somewhere with such a function. You can also write
one simply.
I usually use the following:
s/^\s+//, s/\s+$// for $variable;
I like that form because you can list a bunch of variables and trim them
all.
A more traditional trim() function could be:
sub trim { local $_ = shift; s/^\s+//, s/\s+$//; $_ }
