hello monks, I am in confusion that whether the problem is with my understanding or am doing something wrong or others. So requesting you to go ease with me in this case. The problem is with the following code 
$| = 1;
$i = 0;

$SIG{'INT'} = 'handler_of_int';
sub handler_of_int { 
	print STDOUT "got END\n"; 
	print STDERR "signal caught...\n"; 
	
	close(stdout); exit(0); 
}

while (1)  {
	print STDOUT ++$i;
	sleep (1);
}
When i execute this way, and give CTRL+C ( sigint ), it prints the 'got END'. 
perl write.pl
123^Cgot END
signal caught...
But when i execute this same program using tee command, the 'got END' is not getting printed either to file or to stdout. ( tee - read from standard input and write to standard output and files ) 
perl write.pl | tee file
12^Csignal caught...

cat file
12
Whats wrong with this ?!
