WHACK(1)                    General Commands Manual                   WHACK(1)

       whack - mangle requests to a printer or damage a printer

       whack [-h | -v] [-i] [-w] ids

       whack [-j] [-v] [-s] [-w] printers

       whack mangles line printer requests or damages line printers.  When the
       first form of the command is used, the printed output  of  the  job  is
       mangled  as  specified by the options. When the second form of the com-
       mand is used, the  printer  itself  is  damaged  as  specified  by  the

       -h        Horizontal. Make the output run across the page horizontally,
                 ignoring linefeeds and  other  form  movement  characters  or
                 embedded commands.

       -v        Vertical.  Make  the output run vertically in one column (the
                 current column) down the paper, ignoring  any  form  movement
                 characters or embedded commands.

       -i        ISO  mode. Select, at random, a different ISO code set to use
                 while printing the rest of the job.

       -w        Write a taunting message on the  user's  terminal  after  the
                 jobs  have  been  whacked.   If  the  user  is  not logged in
                 locally, then mail will be sent instead.

       -j        Jam. Self-explanitory.

       -v        Voltage surge. Send a voltage spike down the transmit lead(s)
                 of  the printer.  Physical contact with the printer should be
                 avoided while using the -v option.

       -s        Spit. Causes the printer to rapidly  eject  it's  paper  load
                 into  the  output bin.  Depending upon the speed of the ejec-
                 tion, a few characters could actually print on each page.
