A summary of typographical conventions is shown in Table 2-1. The Bold Courier font is used to show brackets that denote optional arguments in a utility synopsis, as in cut [-_c _l_i_s_t] [_f_i_l_e__n_a_m_e] These brackets shall not be used by the application unless they are specifically mentioned as literal input characters by the utility description. There are two types of symbols enclosed in angle brackets (< >): C-Language Headers The header name is in the Courier font, such as . When coding C programs, the brackets are used as required by the language. Parameters Parameters, also called _m_e_t_a_v_a_r_i_a_b_l_e_s, are in italics, such as <_d_i_r_e_c_t_o_r_y _p_a_t_h_n_a_m_e>. The entire symbol, including the brackets, is meant to be replaced by the value of the symbol described within the brackets. Numbers within braces, such as ``POSIX.1 {8},'' represent cross references to the Normative References clause (see 1.2). If the number is preceded by a B, it represents a Bibliographic entry (see Annex D). Bibliographic entries are for information only. In some examples, the Bold Courier font is used to indicate the system's output that resulted from some user input, shown in Courier. Copyright c 1991 IEEE. All rights reserved.
