Hejsa,

prøv med
$|=1;

Fra perlvar siden:

$|

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 getc in the perlfunc manpage for that. (Mnemonic:
when you want your pipes to be piping hot.)
