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, ignor-
ing any form movement characters or embedded com-
mands.
-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.
