Note: if 23 .Ar file 24 contains format input for a preprocessor, the commands shown 25 above must be piped through the appropriate preprocessor. This is handled 26 automatically by the 27 .Xr man 1 28 command. See the 29 .Sx Conventions 30 section. 31 .Lp 32 Any text argument 33 .Ar t 34 may be zero to six words. Quotes may be used to 35 include SPACE characters in a 36 .Qq word . 37 If 38 .Ar text 39 is empty, the special 40 treatment is applied to the next input line with text to be printed. In this 41 way 42 .Nm \&.I 43 may be used to italicize a whole line, or 44 .Nm \&.SB 45 may be used to make small bold letters. 46 .Lp 47 A prevailing indent distance is remembered between successive indented 48 paragraphs, and is reset to default value upon reaching a non-indented 49 paragraph. Default units for indents 50 .Nm i 51 are ens. 52 .Lp 53 Type font and size are reset to default values before each paragraph, and after 54 processing font and size setting macros. 55 .Pp 56 These strings are predefined by 57 .Nm -man : 58 .Bl -tag -width Ds 59 .It Nm \e*R 60 .Sq \(rg , 61 .Sq (Reg) 62 in 63 .Nm nroff . 64 .It Nm \e*S 65 Change to default type size. 66 .El 67 .Sh "Requests" 68 * n.t.l. = next text line; p.i. = prevailing indent 69 .Bl -column ".TH n s d f m" "Cause " "t=n.t.l.*" "Explanation " -offset Ds 70 .It Sy Request Sy Cause Sy "If No" Sy Explanation 71 .It "" Sy Break Sy "Argument" "" 72 .It Nm \&.B Ar "t" no Ar t Ns =n.t.l.* Text is in bold font. 73 .It Nm \&.BI Ar t no Ar t Ns =n.t.l.

Section Subheading. 100 .It Nm \&.TH Ar n s d f m yes - Begin reference page Ar n , No of section Ar s ; Ar d No is the date of the most recent change. If present, Ar f No is the left page footer; Ar m No is the main page (center) header. Sets prevailing indent and tabs to .5i. 101 .It Nm \&.TP Ar i yes Ar i Ns =p.i. Begin indented paragraph, with the tag given on the next text line. Set prevailing indent to 102 .Ar i . 103 .It Nm \&.TX Ar t p no - Resolve the title abbreviation Ar t ; No join to punctuation mark (or text) Ar p . 104 .El 105 .Ss "Conventions" 106 When formatting a manual page, 107 .Nm 108 examines the first line to determine 109 whether it requires special processing. For example a first line consisting of: 110 .Lp 111 .Dl \&'\e" t 112 .Lp 113 indicates that the manual page must be run through the 114 .Xr tbl 1 115 preprocessor. 116 .Lp 117 A typical manual page for a command or function is laid out as follows: 118 .Bl -tag -width ".SH RETURN VALUES" 119 . 120 .It Nm \&.TH Ar title Op "1-9" 121 . 122 The name of the command or function, which serves as the title of the manual 123 page. This is followed by the number of the section in which it appears. 124 . 125 .It Nm SH NAME 126 . 127 The name, or list of names, by which the command is called, followed by a dash 128 and then a one-line summary of the action performed. All in roman font, this 129 section contains no 130 .Xr troff 1 131 commands or escapes, and no macro requests. 132 It is used to generate the database used by the 133 .Xr whatis 1 134 command. 135 . 136 .It Nm SH SYNOPSIS 137 .Bl -tag -width "Functions:" 138 .It Sy Commands: 139 The syntax of the command and its arguments, as typed on the command line. 140 When in boldface, a word must be typed exactly as printed. When in italics, a 141 word can be replaced with an argument that you supply. References to bold or 142 italicized items are not capitalized in other sections, even when they begin a 143 sentence. 144 .Lp 145 Syntactic symbols appear in roman face: 146 .Bl -tag -width " " 147 .It Op " " 148 An argument, when surrounded by brackets is optional. 149 .It | 150 Arguments separated by a vertical bar are exclusive. You can supply only one 151 item from such a list. 152 .It \&.\|.\|. 153 Arguments followed by an ellipsis can be repeated. When an ellipsis follows a 154 bracketed set, the expression within the brackets can be repeated. 155 .El 156 .It Sy Functions: 157 If required, the data declaration, or 158 .Li #include 159 directive, is shown first, 160 followed by the function declaration. Otherwise, the function declaration is 161 shown. 162 .El 163 . 164 .It Nm \&.SH DESCRIPTION 165 . 166 A narrative overview of the command or function's external behavior. This 167 includes how it interacts with files or data, and how it handles the standard 168 input, standard output and standard error. Internals and implementation details 169 are normally omitted. This section attempts to provide a succinct overview in 170 answer to the question, "what does it do?" 171 .Lp 172 Literal text from the synopsis appears in constant width, as do literal 173 filenames and references to items that appear elsewhere in the reference 174 manuals. Arguments are italicized. 175 .Lp 176 If a command interprets either subcommands or an input grammar, its command 177 interface or input grammar is normally described in a 178 .Nm USAGE 179 section, which follows the 180 .Nm OPTIONS 181 section. The 182 .Nm DESCRIPTION 183 section only 184 describes the behavior of the command itself, not that of subcommands. 185 . 186 .It Nm \&.SH OPTIONS 187 . 188 The list of options along with a description of how each affects the command's 189 operation. 190 . 191 .It Nm \&.SH RETURN VALUES 192 . 193 A list of the values the library routine will return to the calling program 194 and the conditions that cause these values to be returned. 195 . 196 .It Nm \&.SH EXIT STATUS 197 . 198 A list of the values the utility will return to the calling program or shell, 199 and the conditions that cause these values to be returned. 200 . 201 .It Nm \&.SH FILES 202 . 203 A list of files associated with the command or function. 204 . 205 .It Nm \&.SH SEE ALSO 206 . 207 A comma-separated list of related manual pages, followed by references to other 208 published materials. 209 . 210 .It Nm \&.SH DIAGNOSTICS 211 . 212 A list of diagnostic messages and an explanation of each. 213 . 214 .It Nm \&.SH BUGS 215 . 216 A description of limitations, known defects, and possible problems associated 217 with the command or function. 218 .El 219 .Sh FILES 220 .Pa /usr/share/man/whatis 221 .Sh NOTES 222 The 223 .Nm 224 package should not be used for new documentation. The 225 .Xr mdoc 5 , 226 package is preferred, as it uses semantic markup rather than physical markup. 227 .Sh CODE SET INDEPENDENCE 228 When processed with 229 .Xr mandoc 1 , 230 this package is Code Set Independent. However, when processed with 231 legacy tools such as 232 .Xr nroff 1 233 and 234 .Xr troff 1 , 235 the use of multi-byte characters may not be supported. 236 .Sh INTERFACE STABILITY 237 .Nm Obsolete Committed . 238 The 239 .Xr mdoc 5 240 package should be used instead. 241 .Sh SEE ALSO 242 .Xr eqn 1 , 243 .Xr man 1 , 244 .Xr mandoc 1 , 245 .Xr nroff 1 , 246 .Xr troff 1 , 247 .Xr tbl 1 , 248 .Xr whatis 1 , 249 .Xr mdoc 5 , 250 .Rs 251 .%A Dale Dougherty and Tim O'Reilly 252 .%B Unix Text Processing 253 .Re
