lptest - generate lineprinter ripple pattern
lptest [length] [count]
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
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. Note that if
count is to
be specified, length must be also be specified.
lptest appeared in 4.3BSD.
OpenBSD 3.6 December 30, 1993
