    Here's a version for you (preserving its behavior) that'll work on Unix and Win32.
    $_=('%#(/@*(((@!./((%)@+%),@(!#+%)@'.(($^O^'`.*).dn')eq'-}}@@W\\'? '#/.{o|~{':'o$%-`(*"'))^'@@@@``][\`@@@\@@[`{@[@`@@@@@[~@@@[O\\^[';`$_`

    Huh. Just when I think I have a glimpse of the workings of Perl, I find this. Anyone care to point out what makes this one tick?

      This one's fairly simple, actually. There are really only two parts: An assignment to $_ and a back-tick running of $_.

      If you break down the first statement, you'll see it's two strings XOR'd together:

      $_ = '%#(/@*(((@!./((%)@+%),@(!#+%)@#/.' # The encrypted string ^ # XOR '@@@@``][\`@@@\@@[`{@[@`@@@@@[~@@@' # The secret decoder ring

      So this ends up assigning 'echo Just another Perl hacker>con' to $_. The second line, `$_` simply passes that to the shell and runs it, which will work fine on any Win32 system.

        Thanks for the help!

    It also works on NT4 and Win2000 with ActiveState Perl 5.6.

    Very cool :) How on earth does it work?
