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, 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 ejection, a few
characters could actually print on each page.
