in reply to Capturing top-like program output

Try taking a look at the man pages for top. If you open it in batch mode (-b) with a single iteration (-n 1), I'm guessing you could capture the output of a single update from top. Process that output, save it, display it or whatever you wanted to do with it, then fetch another screen of output.

Completely untested: 

my $n = 1;
while( $n < 5 ) {
    # capture a single screen's worth of output...
    my $temp = `top -b -n 1`;

    # process $temp here...

    # play nice
    sleep 15;

    $n = $n + 1;
    }

    I realize that that -b switch is the simplest answer to Alien's question, but personally, I still wonder how you would capture raw console writes from perl.
