LPTEST(1) 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 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 debugā€ ging purposes, 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 4.3 Berkeley Distribution April 29, 1985 LPTEST(1)
