on second thought..this doesn't work that well with more then one fd open...it hangs on close($fd). Maybe there's an error in my code:
print "I'm $$\n;"; use FileHandle; $fh = new FileHandle; $fh1 = new FileHandle; my $sleep_count = 0; do { $pid = open($fh, "|-"); unless (defined $pid) { warn "cannot fork: $!"; die "bailing out" if $sleep_count++ > 6; sleep 10; } } until defined $pid; if ($pid) { print "I'm master($$) $pid...\n"; } else { print "Waiting for commands($$)..\n"; while (<STDIN>) { print "GOT: $_\n"; # child's STDIN is parent's KID } exit; # don't forget this }; do { $pid1 = open($fh1, "|-"); unless (defined $pid1) { warn "cannot fork: $!"; die "bailing out" if $sleep_count++ > 6; sleep 10; } } until defined $pid1; if ($pid1) { print "I'm master($$) $pid1...\n"; } else { print "Waiting for commands($$)..\n"; while (<STDIN>) { print "GOT: $_\n"; # child's STDIN is parent's KID } exit; # don't forget this }; my (@some_data)=qw[a be ce]; print "($$)PID: $pid\n"; print $fh @some_data; print "($$) printing done, let's close:\n"; close($fh) || warn "kid exited $?"; print "($$)PID: $pid1\n"; print $fh1 @some_data; print "($$) printing done, let's close:\n"; close($fh1) || warn "kid exited $?"; print "END FH TEST\n\n\n";
