That is true. The advantage of checking the file size first is that it is a very quick test that does not require reading the entire file. You can get the file size in Perl one of two ways: 1. my $size = (stat($filename))[7]; or 2. my $size = -s $filename; -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
