Re^3: Issue with communication of large data between Parent and child using Perl pipes

Thanks! ikegami!

open(my $pipe, "$command |")    # 2-arg form
open(my $pipe, '-|', $command)  # 3-arg form
[download]

above looks right, this 2 arg form from OP looked weird to me:

 
$pid=open(PARENT_READ_HANDLE, "-|");
[download]

Which as they say is neither fish or fowl (not correct 2-arg or 3 arg). I am still a bit confused as to the OP's intent here. This still appears to be a synchronous app, not client-server. There is a lot of complex stuff that doesn't appear to be necessary.
