  23 .SH DESCRIPTION
  24 .sp
  25 .LP
  26 The \fBman\fR command displays information from the reference manuals. It
  27 displays complete manual pages that you select by \fIname\fR, or one-line
  28 summaries selected either by \fIkeyword\fR (\fB-k\fR), or by the name of an
  29 associated file (\fB-f\fR). If no manual page is located, \fBman\fR prints an
  30 error message.
  31 .SS "Source Format"
  32 .sp
  33 .LP
  34 Reference Manual pages are marked up with either \fBnroff\fR (see
  35 \fBnroff\fR(1)) or \fBSGML\fR (Standard Generalized Markup Language) tags (see
  36 \fBsgml\fR(5)). The \fBman\fR command recognizes the type of markup and
  37 processes the file accordingly. The various source files are kept in separate
  38 directories depending on the type of markup.
  39 .SS "Location of Manual Pages"
  40 .sp
  41 .LP
  42 The online Reference Manual page directories are conventionally located in
  43 \fB/usr/share/man\fR. The nroff sources are located in the
  44 \fB/usr/share/man/man\fR* directories. The \fBSGML\fR sources are located in
  45 the \fB/usr/share/man/sman\fR* directories. Each directory corresponds to a
  46 section of the manual. Since these directories are optionally installed, they
  47 might not reside on your host. You might have to mount \fB/usr/share/man\fR
  48 from a host on which they do reside.
  49 .sp
  50 .LP
  51 If there are preformatted, up-to-date versions in the corresponding \fBcat\fR*
  52 or \fBfmt\fR* directories, \fBman\fR simply displays or prints those versions.
  53 If the preformatted version of interest is out of date or missing, \fBman\fR
  54 reformats it prior to display and stores the preformatted version if \fBcat\fR*
  55 or \fBfmt\fR* is writable. The \fBwindex\fR database is not updated. See
  56 \fBcatman\fR(1M). If directories for the preformatted versions are not
  57 provided, \fBman\fR reformats a page whenever it is requested. \fBman\fR uses a
  58 temporary file to store the formatted text during display.
  59 .sp
  60 .LP
  61 If the standard output is not a terminal, or if the `\fB-\fR' flag is given,
  62 \fBman\fR pipes its output through \fBcat\fR(1). Otherwise, \fBman\fR pipes its
  63 output through \fBmore\fR(1) to handle paging and underlining on the screen.
  64 .SH OPTIONS

  85 searching, and paths searched by \fBman\fR.
  86 .RE

  89 .ne 2
  90 .na
  91 \fB\fB-f\fR \fIfile ...\fR\fR
  92 .ad
  93 .RS 20n
  94 \fBman\fR attempts to locate manual pages related to any of the given
  95 \fIfile\fRs. It strips the leading path name components from each \fIfile\fR,
  96 and then prints one-line summaries containing the resulting basename or names.
  97 This option also uses the \fBwindex\fR database.
  98 .RE
  99 
 100 .sp
 101 .ne 2
 102 .na
 103 \fB\fB-F\fR\fR
 104 .ad
 105 .RS 20n
 106 Forces \fBman\fR to search all directories specified by \fBMANPATH\fR or the
 107 \fBman.cf\fR file, rather than using the \fBwindex\fR lookup database. This
 108 option is useful if the database is not up to date and it has been made the
 109 default behavior of the \fBman\fR command. The option therefore does not have
 110 to be invoked and is documented here for reference only.
 111 .RE
 112 
 113 .sp
 114 .ne 2
 115 .na
 116 \fB\fB-k\fR \fIkeyword ...\fR\fR
 117 .ad
 118 .RS 20n
 119 Prints out one-line summaries from the \fBwindex\fR database (table of
 120 contents) that contain any of the given \fIkeyword\fRs. The \fBwindex\fR
 121 database is created using \fBcatman\fR(1M).

 124 .sp
 125 .ne 2

 134 .ne 2
 135 .na
 136 \fB\fB-M\fR \fIpath\fR\fR
 137 .ad
 138 .RS 20n
 139 Specifies an alternate search path for manual pages. \fIpath\fR is a
 140 colon-separated list of directories that contain manual page directory
 141 subtrees. For example, if \fIpath\fR is \fB/usr/share/man:/usr/local/man\fR,
 142 \fBman\fR searches for \fIname\fR in the standard location, and then
 143 \fB/usr/local/man\fR. When used with the \fB-k\fR or \fB-f\fR options, the
 144 \fB-M\fR option must appear first. Each directory in the \fIpath\fR is assumed
 145 to contain subdirectories of the form \fBman\fR* or \fBsman\fR* , one for each
 146 section. This option overrides the \fBMANPATH\fR environment variable.

 149 .sp
 150 .ne 2
 151 .na
 152 \fB\fB-r\fR\fR
 153 .ad
 154 .RS 20n
 155 Reformats the manual page, but does not display it. This replaces the \fBman\fR
 156 \fB-\fR \fB-t\fR \fIname\fR combination.
 157 .RE

 160 .ne 2
 161 .na
 162 \fB\fB-s\fR \fIsection ...\fR\fR
 163 .ad
 164 .RS 20n
 165 Specifies sections of the manual for \fBman\fR to search. The directories
 166 searched for \fIname\fR are limited to those specified by \fIsection\fR.
 167 \fIsection\fR can be a numerical digit, perhaps followed by one or more letters
 168 to match the desired section of the manual, for example, "\fB3libucb\fR". Also,
 169 \fIsection\fR can be a word, for example, \fBlocal\fR, \fBnew\fR, \fBold\fR,
 170 \fBpublic\fR. \fIsection\fR can also be a letter. To specify multiple sections,
 171 separate each section with a comma. This option overrides the \fBMANPATH\fR
 172 environment variable and the \fBman.cf\fR file. See \fBSearch\fR \fBPath\fR
 173 below for an explanation of how \fBman\fR conducts its search.

 181 .RS 20n
 182 \fBman\fR arranges for the specified manual pages to be \fBtroff\fRed to a
 183 suitable raster output device (see \fBtroff\fR(1)). If both the \fB-\fR and
 184 \fB-t\fR flags are given, \fBman\fR updates the \fBtroff\fRed versions of each
 185 named \fIname\fR (if necessary), but does not display them.

 212 
 213 .SH USAGE
 214 .sp
 215 .LP
 216 The usage of \fBman\fR is described below:
 217 .SS "Manual Page Sections"
 218 .sp
 219 .LP
 220 Entries in the reference manuals are organized into \fIsection\fRs. A section
 221 name consists of a major section name, typically a single digit, optionally
 222 followed by a subsection name, typically one or more letters. An unadorned
 223 major section name, for example, "\fB9\fR", does not act as an abbreviation for
 224 the subsections of that name, such as "\fB9e\fR", "\fB9f\fR", or "\fB9s\fR".
 225 That is, each subsection must be searched separately by \fBman\fR \fB-s\fR.
 226 Each section contains descriptions apropos to a particular reference category,
 227 with subsections refining these distinctions. See the \fBintro\fR manual pages
 228 for an explanation of the classification used in this release.
 229 .SS "Search Path"
 230 .sp
 231 .LP
 232 Before searching for a given \fIname\fR, \fBman\fR constructs a list of
 233 candidate directories and sections. \fBman\fR searches for \fIname\fR in the
 234 directories specified by the \fBMANPATH\fR environment variable.
 235 .sp
 236 .LP
 237 In the absence of \fBMANPATH\fR, \fBman\fR constructs its search path based
 238 upon the \fBPATH\fR environment variable, primarily by substituting \fBman\fR
 239 for the last component of the \fBPATH\fR element. Special provisions are added
 240 to account for unique characteristics of directories such as \fB/sbin\fR,
 241 \fB/usr/ucb\fR, \fB/usr/xpg4/bin\fR, and others. If the file argument contains
 242 a \fB/\fR character, the \fIdirname\fR portion of the argument is used in place
 243 of \fBPATH\fR elements to construct the search path.
 244 .sp
 245 .LP
 246 Within the manual page directories, \fBman\fR confines its search to the
 247 sections specified in the following order:
 248 .RS +4
 249 .TP
 250 .ie t \(bu
 251 .el o
 252 \fIsection\fRs specified on the command line with the \fB-s\fR option
 253 .RE
 254 .RS +4
 255 .TP
 256 .ie t \(bu
 257 .el o
 258 \fIsection\fRs embedded in the \fBMANPATH\fR environment variable
 259 .RE
 260 .RS +4
 261 .TP
 262 .ie t \(bu
 263 .el o
 264 \fIsection\fRs specified in the \fBman.cf\fR file for each directory specified
 265 in the \fBMANPATH\fR environment variable
 266 .RE
 267 .sp
 268 .LP
 269 If none of the above exist, \fBman\fR searches each directory in the manual
 270 page path, and displays the first matching manual page found.
 271 .sp
 272 .LP
 273 The \fBman.cf\fR file has the following format:
 274 .sp
 275 .in +2
 276 .nf
 277 MANSECTS=\fIsection\fR[,\fIsection\fR]...
 278 .fi
 279 .in -2
 280 .sp
 281 
 282 .sp
 283 .LP
 284 Lines beginning with `\fB#\fR' and blank lines are considered comments, and are
 285 ignored. Each directory specified in \fBMANPATH\fR can contain a manual page
 286 configuration file, specifying the default search order for that directory.
 287 .SH FORMATTING MANUAL PAGES
 288 .sp
 289 .LP
 290 Manual pages are marked up in \fBnroff\fR(1) or \fBsgml\fR(5). Nroff manual
 291 pages are processed by \fBnroff\fR(1) or \fBtroff\fR(1) with the \fB-man\fR
 292 macro package. Please refer to \fBman\fR(5) for information on macro usage.
 293 \fBSGML\fR\(emtagged manual pages are processed by an \fBSGML\fR parser and
 294 passed to the formatter.
 295 .SS "Preprocessing Nroff Manual Pages"
 296 .sp
 297 .LP
 298 When formatting an nroff manual page, \fBman\fR examines the first line to
 299 determine whether it requires special processing. If the first line is a string
 300 of the form:
 301 .sp
 302 .in +2
 303 .nf
 304 \&'\e" \fIX\fR

 311 where \fIX\fR is separated from the `\fB"\fR' by a single SPACE and consists of

 353 \fB/usr/pub/eqnchar\fR (see \fBeqnchar\fR(5)). If \fBnroff\fR(1) is invoked,
 354 \fBcol\fR(1) is automatically used.
 355 .SS "Referring to Other nroff Manual Pages"
 356 .sp
 357 .LP
 358 If the first line of the nroff manual page is a reference to another manual
 359 page entry fitting the pattern:

 372 page directory subtree.
 373 .sp
 374 .LP
 375 When the second or any subsequent line starts with \fB\&.so\fR, \fBman\fR
 376 ignores it; \fBtroff\fR(1) or \fBnroff\fR(1) processes the request in the usual
 377 manner.
 378 .SS "Processing SGML Manual Pages"
 379 .sp
 380 .LP
 381 Manual pages are identified as being marked up in SGML by the presence of the
 382 string \fB<!DOCTYPE\fR\&. If the file also contains the string
 383 \fBSHADOW_PAGE\fR, the file refers to another manual page for the content. The
 384 reference is made with a file entity reference to the manual page that contains
 385 the text. This is similar to the \fB\&.so\fR mechanism used in the nroff
 386 formatted man pages.

 640 The \fB-f\fR and \fB-k\fR options use the \fBwindex\fR database, which is
 641 created by \fBcatman\fR(1M).

 643 .LP
 644 The \fBman\fR command is CSI-capable. However, some utilities invoked by the
 645 \fBman\fR command, namely, \fBtroff\fR, \fBeqn\fR, \fBneqn\fR, \fBrefer\fR,
 646 \fBtbl\fR, and \fBvgrind\fR, are not verified to be CSI-capable. Because of
 647 this, the man command with the \fB-t\fR option can not handle non-EUC data.
 648 Also, using the \fBman\fR command to display man pages that require special
 649 processing through \fBeqn\fR, \fBneqn\fR, \fBrefer\fR, \fBtbl\fR, or
 650 \fBvgrind\fR can not be CSI-capable.
 651 .SH BUGS
 652 .sp
 653 .LP
 654 The manual is supposed to be reproducible either on a phototypesetter or on an
 655 \fBASCII\fR terminal. However, on a terminal some information (indicated by
 656 font changes, for instance) is lost.
 657 .sp
 658 .LP
 659 Some dumb terminals cannot process the vertical motions produced by the \fBe\fR
 660 (see \fBeqn\fR(1)) preprocessing flag. To prevent garbled output on these
 661 terminals, when you use \fBe\fR, also use \fBt\fR, to invoke \fBcol\fR(1)
 662 implicitly. This workaround has the disadvantage of eliminating superscripts
 663 and subscripts, even on those terminals that can display them. Control-q clears
 664 a terminal that gets confused by \fBeqn\fR(1) output.
