lptest(1BSD) (BSD System Compatibility) lptest(1BSD)
NAME
lptest - (BSD) 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
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.
NOTICES
If count is to be specified, length must be also be specified.
This command is obsolescent.
