Try this code....either of these might be what you're looking for
#!/usr/bin/perl
#
use warnings;
use strict;
print "printing 1thru5 with buffering\n";
select undef, undef, undef, 0.25 or print $_
for 1 .. 5;
print "\nflush forced\n";
$|++;
print "printing 1thru5 without buffering\n";
select undef, undef, undef, 0.25 or print $_
for 1 .. 5;
print "\nflush forced\n";
