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
-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.
