  lptest(1)                           CLIX                           lptest(1)



  NAME

    lptest - Generates line printer ripple test pattern

  SYNOPSIS

    lptest [length [count]]

  DESCRIPTION

    The lptest command writes the traditional ``ripple test'' pattern on
    stdout.  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 characters is inappropriate.  The count argument specifies the
    number of output lines to be generated if the default count of 200 lines
    is inappropriate.

  EXAMPLES

    The following produces a test pattern 72 characters wide by 5 lines long:

    $ lptest 72 5
    !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefgh
    "#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghi
    #$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghij
    $%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijk
    %&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijkl
