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 ori-
ginally created to test printers, it is quite useful for
testing terminals, driving terminal ports for debugging pur-
poses, 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 speci-
fied. This command is obsolescent.
