NAME
lptest - Generates the line printer ripple test pattern
SYNOPSIS
lptest [length [count]]
FLAGS
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
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 character-column 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.
