SYNOPSIS

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

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

DESCRIPTION

    whack mangles line printer requests or damages line print-
    ers.  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 embed-
              ded 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  con-
              tact  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.
