Hello,
I changed your codes like below:
use strict;
for (my $i=0;$i<2;++$i) {
my $pid = open CHILD,"|-";
select CHILD;$|++;select STDOUT;
if ($pid) {
print CHILD "/etc/passwd";
}else {
my $c = <>;
exec "/bin/cat $c";
}
}
__END__
The parent doesn't get blocked when it finished writing to the childs.It is
that,when the parent finished the "print CHILD",it should continue for the next
loop,while the childs should do the things they wanted.The childs can't block
the parent except that they must read lots of datas from parent then it maybe
slow the parent's writting action (due to the buffer).
