To elaborate a bit on FunkyMonk's response, the period (.), when used in regular expressions means "any character except1 the newline." The way split is to break a string into fields, throwing out the specified separator2, which is a regular expression. When I try splitting a string with /./, I get an empty array.
If you want to split a string on periods (.), you've got to escape it, with the backslash (\), so your split should look something like this:
@file = split(/\./, $file_name);
(which is exactly what FunkyMonk wrote).
Regex are fun, and an incredibly powerful part of Perl.
1: Usually.
2: Although you can keep it if you want, by surrounding the regex with parentheses.
