NAME
lptest - generate lineprinter ripple pattern
SYNOPSIS
/usr/ucb/lptest [ length [ count ] ]
DESCRIPTION
lptest 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 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.
NOTES
if count is to be specified, length must be also be specified.
This command is obsolescent.
