Re: Use of uninitialized value in numeric gt (>)

The problem is -s returns undef if the file does not exist. Then undef causes the 'uninitialized' warning. One fix for this is to set $flag_size to 0 when -s returns undef:

my $flag_size = -s 'online.flg' || 0;

Thankyou, and everyone who replied. I will now go and check but I recon your right. The file did not exist. I will check out -f as all I really want to do is know if a file exists I dont really care what size it is if it does exist. Ideally Id like to do this: `my $offline = -f 'online.flg';` [download] ..with the hope that it will return false if the file doesn't exist (without raising a warning) - thus achieving my aim.
