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 out-
put. In 96 lines, this pattern will print all 96 printable ASCII char-
acters 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 default
length of 79 is inappropriate.
The count argument specifies the number of output lines to be gen-
erated if the default count of 200 is inappropriate.
NOTES
If count is to be specified, length must be also be specified.
