LPTEST(1)		    General Commands Manual		     LPTEST(1)

NAME
       lptest -- generate lineprinter ripple pattern

SYNOPSIS
       lptest [length] [count]

DEPRECATION NOTICE
       This  facility  is  scheduled  for  removal  prior  to  the  release of
       FreeBSD 16.0.

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	16.0 CURRENT	       December	30, 1993		     LPTEST(1)
