LPTEST(1) UNIX Programmer's Manual LPTEST(1) NAME lptest - generate lineprinter ripple pattern SYNOPSIS lptest [ length [ count ] ] DESCRIPTION _L_p_t_e_s_t writes the traditional "ripple test" pattern on stan- dard output. In 96 lines, this pattern will print all 96 printable ASCII characters in each position. While origi- nally created to test printers, it is quite useful for test- ing terminals, driving terminal ports for debugging pur- poses, or any other task where a quick supply of random data is needed. The _l_e_n_g_t_h argument specifies the output line length if the the default length of 79 is inappropriate. The _c_o_u_n_t argument specifies the number of output lines to be generated if the default count of 200 is inappropriate. Note that if _c_o_u_n_t is to be specified, _l_e_n_g_t_h must be also be specified. SEE ALSO BUGS Printed 11/26/99 April 29, 1985 1
