Erk! This code:
open FILE, $logfile || die $!;
does not act the way you want it to. Because the
|| has a higher precedence than the comma, what
actually happens is this:
open FILE, ($logfile || die $!);
for the complete precedence list.
If you really want to use the || then put
parenthesis around things like so:
open (FILE, $logfile) || die "Could not open $logfile: $!\n";
Better yet, use the super-low-priority or, which allows
you to acheive your original effect:
open FILE, $logfile or die "Could not open $logfile: $!\n";
Best of all, be correct and non-ambigous and use both:
open (FILE< $logfile) or die "Could not open $logfile: $!\n";
