The processor utilization would be a concern if it's constant; but cgi
programs usually aren't. Nevertheless, I would suggest a secured standard
irc server with a web interface that php will easily do (See Application
Development with PHP 4.0, 2000, New Riders)

mdrecoveryd insures devices sponsored by software RAID are synchronized
correctly at shutdown. It's default on RedHat, though I don't know why
the Raqs use it, it may literally be a superfluous process in this case,
which reminds me of MS; but nevermind that now. It's a kernel process which
you can determine by looking at the output of the ps command; and cannot
readily
disable for that reason.

I can't get it to work with top because the output is binary; but I figure
ps
is pretty informative as well so here ya go, set target to the number of
lines
you want to return. I wrote it this way because I figure seeing multiple
lines
has more utility. you could also call it like:

include test.php?target=N for quick editing to suit different users

<?php
$cmd = "ps -aux";
$target = 20;
$lines = 0;

if (!exec($cmd, $myOutput)) {
echo "Guess that didn't work";
exit();
}

while($lines < $target) {
echo "$myOutput[$lines]<BR>\n";
$lines++;
}
?>

If you really want just the one line  to print, run it like this first, take
the
"echo" line out of the while loop, and set $lines to the value you think has
what
you want, rembering that the first line number is 0.

I just used <BR> to break the lines for readability; but you may want to do
more
sophisticated formatting.
