I have a piece of code this way: 
use File::Tail;

$SIG{'INT'} = 'INT_handler';
sub INT_handler {
    open(FILE,"/tmp/filename") || die "Cannot open file:$!";
    $cur_filename=<FILE>;
    close(FILE);

    print("Don't Interrupt!\n");
    chomp($cur_filename);
    
    $file=File::Tail->new(name=>$cur_filename, maxinterval=>3, adjusta
+fter=>2,tail=>-1);
 }   
    
    
$cur_filename=$ARGV[0];
$file=File::Tail->new(name=>$cur_filename, maxinterval=>3, adjustafter
+=>2,tail=>-1);

while (defined($line=$file->read)) {
    print $line;
}

Let me explain my intention. I have a constantly changing log and the log is rotated every hour(so a new log file is created every hour). What i intend to do is have a configuration file which has the current hour's log's filename and every hour I'll change the filename in this config file (externally from a diff prog ) and pass a INTsignal to the above code for it to pick up the newfile name.
But some how this doesnt work. The first time, File::Tail reads the file. But it doesnt read the new one when the INT_handler function handles the signal.
I'm also not sure if what i think is right...looking forward for suggestions.
