I don't think I understand what you are saying. Neither provides data to
perl until you read from $file; however, it is important to note that the
results of the two functions are not the same. The filehandle resulting
from the open contains both STDOUT and STDERR from the command (due to the

Thanks for that, now I have another issue.
Unlike a piped open, open 3 does not seem to produce output immediately
Is there any way to use pipes with open3 so that the FH has content before
looping
ie: this produces output
my $pid=open($file, "-|","$cmd{$sopts->{subname}} 2>&1")
while
$pid=open3

Sounds like you want a named pipe.

Hello,
My problem was that I was creating the SM variable and after a bit the app
was killing the current process witch destroyed the variable.
Sorry (very long script), and thanks for your help.

Hi,
I guess you should not really use IPC::Shareable, it's last release
was ages ago.
It does not succeed tests on a 5.10.x perl:
https://rt.cpan.org/Public/Bug/Display.html?id=41401 - and I guess the
patch in this bug report will get it working for you again.
I guess it would be worthwile findin

I see no usage of "ipc::run" there, did you maybe mean "IPC::Run"?

Hello,
Since this is most likely a modperl question, I suggest you'd better ask
it to modperl list:
http://lists.cpan.org/showlist.cgi?name=modperl-user
Good luck!

The above code could be written like this:

Do you think this is better or worse than the other idiom? I like the

What, you didn't put a newline on the end of the line? Your client is
reading lines, isn't it?
goto top;
Excuse me; I feel unwell. Search the net for "goto considered harmful"

Cheers!
I think I have found the problem.
It turns out that the closing and opening of the pipe is in the wrong place.
This code actually works:
#!/bin/env perl
#
use strict;
use FileHandle;
# Global variables;
my $child = 0;
my $max_child = 60;
