use :
$| =1;
open(COMMAND, " command | ");
while(<COMMAND>){
print STDOUT;
## do whatever you want with $_
}
close COMMAND;
__END__
you can then read the output and print it and whatever.

Subject: Not your average system() question...
I understand how the system command works. I understand the
difference between system() and backticks. My question is this:
I want to make a call to an external program and I want the output
printed to the command line as it is processing, BUT, I also want
the output returned to me so that I can parse and check it for certain
conditions. Basically I need the functionality of both system() and
backticks. How do I accomplish this? I looked into redirecting
STDOUT, but didnt see how it was possible.
HELP PLEASE!
