Oops, I sent that before I was done (sliped with the fingers). The first is more efficient, the second is less typing.
....And actually the second one is incorrect, it should be this: $value =~ s/^\s*(.*)\s*$/$1/; You need to use \s* because one of them might match a space and the other might not. The way you had it would only with if there was both a leading and trailing whitespace char(s). But yes, either will work... although most will recommend the first option due to performance (although it is minimal unless the string is very large).
