NAME    [Toc]    [Back]

       lptest - Generates the line printer ripple test pattern

SYNOPSIS    [Toc]    [Back]

       lptest [length [count]]

OPTIONS    [Toc]    [Back]

       Specifies  the  output  line  length when the 79-character
       default line length is inappropriate.  Specifies the  number
  of  output  lines  to  be  generated when the default
       200-line length is inappropriate.  When  count  is  specified,
 length must also be specified.

DESCRIPTION    [Toc]    [Back]

       The  lptest  command writes a traditional ripple test pattern
 to the standard output. In 96 lines, a  pattern  containing
  all  96 printable ASCII characters in each column
       position of the line is  printed.  In  the  pattern,  each
       printed  character  is  displaced rightward one charactercolumn
 on each successive line. Originally created to test
       printers, the ripple test pattern is also useful for testing
 terminals, driving terminal  ports  during  debugging,
       and  for any other diagnostic task where a quick output of
       randomized data is needed.
