os (1) --- convert backspaces to line printer overstrikes 10/17/82 _U_s_a_g_e os { -l | -x } _D_e_s_c_r_i_p_t_i_o_n 'Os' is a filter that may be used to convert backspaces (such as those produced by the formatter for underlining and boldfacing) into standard Fortran line printer carriage control codes. If the output of 'os' is spooled, the Fortran forms control mode must be in effect. Use of the "f" option on the 'sp' command or the "f" option in a "/dev/lps" pathname (e.g. "/dev/lps/f") will enable Fortran forms control. If the "-x" option is included, 'os' will attempt to generate output for a Printronix printer. We are told that these printers can overprint only a single line, and the characters on that line can only be underscores. Under "-x", 'os' emits only the overstriking that can be performed on these printers. 'Os' will generate a page-eject at the bottom of each page (to keep the pages correct in case of a paper jam). The is the number of lines per output page. If is omitted, 'os' assumes 66 (standard paper). _E_x_a_m_p_l_e_s fmt report | os | sp / f junk> os >/dev/lps/f/bjunk _M_e_s_s_a_g_e_s "Usage: os ..." for invalid argument syntax. _S_e_e _A_l_s_o sp (1), fos (1) os (1) - 1 - os (1)
