Capture output but suppress it to screen

Hello,
Using perl with cygwin, i want to run an executable and capture its output but supress what is normally viewed in the console.

Say I run a dos box and type  "program.exe" and the screen outputs:

hello
how are you

What I want is to run "perl.exe test.pl" with the following script

print "this is all that should show on screen"
$output=`program.exe`;

and somehow supress the normal "hello how are you" output from showing on the screen.

Any ideas?

I'll raise points if this proves to be more complicated.

nevermind... my question actually answered itself.

It seems that $output=`program.exe` DOES suppress the video output :P

So first person to put anything remotely intelligent, funny, or something other than "give me the points" gets the points.  Have a good one.

Yes.  `command` suppresses the output (more precisely, it puts it into $output).

Another option is:

open CMD, 'command |' or die "could not open pipe: $!";
while (<CMD>) {
    # do whatever you want with each line of output
}
close CMD;
