in thread monitor.pl

OS => $ , is supposed to be $^O, in other words,
$<ctrl>O. I don't know why It doesn't show up,
there, but if you click the d/l code it should work.
What I did was right click d/l code, save it to disk,
then strip out the ^M's.

    Well, I made sure to right-click and save the code that way (last time I had clicked the d/l link and pasted the code into emacs, which generally works) and despite removing the ^M's, no ^O appeared. So I added it in myself, but then when I tried running monitor, I had this problem:

    Illegal division by zero at monitor.pl line 138.

    That line is in drawvals, and it's:

    $swapUsage = $values{useSwap}/$values{totSwap})*100;

    Not quite sure what's going on there. Is a value for totSwap not being added to %values, perhaps?
    FYI, I am running this script using Perl 5.6.1 on Debian/GNU Linux.

      The only thing that I can think of is that the top command
      on your system is not outputting the same info that mine is,
      mine gives:
      load averages: 0.50, 0.47, 0.41 13:03:12 83 processes: 81 sleeping, 1 running, 1 on cpu Memory: 256M real, 128M free, 64M swap in use, 192M swap free PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 14600 baw 1 36 0 32M 21M run 7:30 8.06% netscape

      If the Memory: line is different in your output, then the regex
      that pulls the memory info won't place a value into totSwap. This
      is because i'm using array subscripting to pull the values out of
      the @memInfo array. Try changing $memInfo[?] to where the correct
      swap values would be.

      --xPhase
