in reply to Issue with regex

eq is used for string equality. Use the binding operator =~ to bind a regular expression match against a variable:
$fileName =~ /^\._/;

BTW, as you can see, there's no need to add .* at the end, as the regex doesn't have to match the whole string.

See perlop for details.
