NAME
       whack - mangle requests to a printer or damage a printer

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

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

DESCRIPTION
       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
       command is used, the printer itself is damaged as specified by the
       options.

OPTIONS
       -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
                 ejection, a few characters could actually print on each page.
