lptest(1) (BSD Compatibility Package) lptest(1)
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.
