LPTEST(1)		    General Commands Manual		     LPTEST(1)

NAME
       lptest -- generate lineprinter ripple pattern

SYNOPSIS
       lptest [length] [count]

DESCRIPTION
       The  lptest  utility  writes  the  traditional "ripple test" pattern on
       standard	output.	 In 96 lines, this pattern will	print all 96 printable
       ASCII characters	in each	position.  While originally  created  to  test
       printers,  it  is  quite	useful for testing terminals, driving terminal
       ports for debugging purposes, or	any other task where a quick supply of
       random data is needed.

       The length argument specifies the output	line  length  if  the  default
       length of 79 is inappropriate.

       The count argument specifies the	number of output lines to be generated
       if the default count of 200 is inappropriate.  Note that	if count is to
       be specified, length must be also be specified.

HISTORY
       A lptest	utility	appeared in 4.3BSD.

FreeBSD	14.3		       December	30, 1993		     LPTEST(1)
