[ input [ output ] ]<br /> <br /> == DESCRIPTION ==<br /> _P_t_x generates a permuted index to file _i_n_p_u_t on file _o_u_t_p_u_t<br /> (standard input and output default). It has three phases:<br /> the first does the permutation, generating one line for each<br /> keyword in an input line. The keyword is rotated to the<br /> front. The permuted file is then sorted. Finally, the<br /> sorted lines are rotated so the keyword comes at the middle<br /> of the page. _P_t_x produces output in the form:<br /> <br /> .xx &quot;tail&quot; &quot;before keyword&quot; &quot;keyword and after&quot; &quot;head&quot;<br /> <br /> where .xx may be an _n_r_o_f_f or _t_r_o_f_f(1) macro for user-defined<br /> formatting. The _b_e_f_o_r_e _k_e_y_w_o_r_d and _k_e_y_w_o_r_d _a_n_d _a_f_t_e_r fields<br /> incorporate as much of the line as will fit around the key-<br /> word when it is printed at the middle of the page. _T_a_i_l and<br /> _h_e_a_d, at least one of which is an empty string &quot;&quot;, are<br /> wrapped-around pieces small enough to fit in the unused<br /> space at the opposite end of the line. When original text<br /> must be discarded, `/' marks the spot.<br /> <br /> The following options can be applied:<br /> <br /> -f Fold upper and lower case letters for sorting.<br /> <br /> -t Prepare the output for the phototypesetter; the default<br /> line length is 100 characters.<br /> <br /> -w _n Use the next argument, _n, as the width of the output<br /> line. The default line length is 72 characters.<br /> <br /> -g _n Use the next argument, _n, as the number of characters<br /> to allow for each gap among the four parts of the line<br /> as finally printed. The default gap is 3 characters.<br /> <br /> -o only<br /> Use as keywords only the words given in the _o_n_l_y file.<br /> <br /> -i ignore<br /> Do not use as keywords any words given in the _i_g_n_o_r_e<br /> file. If the -_i and -_o options are missing, use<br /> /usr/lib/eign as the _i_g_n_o_r_e file.<br /> <br /> -b break<br /> Use the characters in the _b_r_e_a_k file to separate words.<br /> In any case, tab, newline, and space characters are<br /> always used as break characters.<br /> <br /> -r Take any leading nonblank characters of each input line<br /> to be a reference identifier (as to a page or chapter)<br /> separate from the text of the line. Attach that iden-<br /> tifier as a 5th field on each output line.<br /> <br /> The index for this manual was generated using _p_t_x.<br /> <br /> == FILES ==<br /> /bin/sort<br /> /usr/lib/eign<br /> <br /> == BUGS ==<br /> Line length counts do not account for overstriking or pro-<br /> portional spacing.<br /> <br /> [[Category:32v man section 1]]</div>
