WHACK(1)		    General Commands Manual		      WHACK(1)

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  com-
       mand  is	 used,	the  printer itself is damaged as specified by the op-
       tions.

OPTIONS
       -h	 Horizontal. Make the output run across	the page horizontally,
		 ignoring linefeeds and	other form movement characters or  em-
		 bedded	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 lo-
		 cally,	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.
