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.
