$OUTPUT_AUTOFLUSH
$|

If  set to nonzero, forces a flush right away and after every write or
print  on  the  currently  selected  output  channel.  Default  is   0
(regardless of whether the channel is really buffered by the system or
not;  $|  tells you only whether you've asked Perl explicitly to flush
after each write). STDOUT will typically be line buffered if output is
to the terminal and block buffered otherwise. Setting this variable is
useful  primarily when you are outputting to a pipe or socket, such as
when  you  are  running  a  Perl program under rsh and want to see the
output  as  it's happening. This has no effect on input buffering. See
perlfunc/getc  for  that.  (Mnemonic:  when  you want your pipes to be
piping hot.)
