"If you don't mind forking, open a filehandle that's a pipe to a tee program:"
And then an example adapted from the same section is:
my ($file1, $file2, $file3) = qw/this.out that.out other.out/;
my $fh;
open $fh, "| tee $file1 $file2 $file3 > /dev/null" or die $!;
print $fh "data\n" or die $!;
close $fh or die $!;
Of course this will only be of value to those whos operating systems support tee (Linux / Unix, for example). The reason for the redirection to /dev/null is because tee typically copies its output on STDOUT. If you don't want that extra copy you redirect it to /dev/null (the garbage can).
