$result is a reference to an array of strings. You can access the actual array via @$result (perlreftut, perlref). You can simply use this to remove the leading whitespace from all the elements of $result: s/^\s+// for @$result;

Update: Also, your sub remove_leadspace is designed to return a modified list of strings, but you're not doing anything with its return value. You could do: @$result = remove_leadspace(@$result); or my @trimmed = remove_leadspace(@$result);
