     man -- format and display the on-line manual pages

     man [-adfhkotw] [-m arch[:machine]] [-p string] [-M path] [-P pager]
	 [-S list] [section] name ...

     The man utility formats and displays the on-line manual pages.  This ver-
     sion knows	about the MANPATH and PAGER environment	variables, so you can
     have your own set(s) of personal man pages	and choose whatever program
     you like to display the formatted pages.  If section is specified,	man
     only looks	in that	section	of the manual.	You may	also specify the order
     to	search the sections for	entries	and which preprocessors	to run on the
     source files via command line options or environment variables.  If en-
     abled by the system administrator,	formatted man pages will also be com-
     pressed with the "/usr/bin/gzip -c" command to save space.

     The options are as	follows:

     -M	path   Specify an alternate manpath.  By default, man uses manpath(1)
	       (which is built into the	man binary) to determine the path to
	       search.	This option overrides the MANPATH environment vari-

     -P	pager  Specify which pager to use.  By default,	man uses "more -s".
	       This option overrides the PAGER environment variable.

     -S	list   List is a colon separated list of manual	sections to search.
	       This option overrides the MANSECT environment variable.

     -a	       By default, man will exit after displaying the first manual
	       page it finds.  Using this option forces	man to display all the
	       manual pages that match name, not just the first.

     -d	       Do not actually display the man pages, but do print gobs	of de-
	       bugging information.

     -f	       Equivalent to whatis.

     -h	       Print a help message and	exit.

     -k	       Equivalent to apropos.

     -m	arch[:machine]
	       As some manual pages are	intended only for specific architec-
	       tures and machine types,	man searches any subdirectories, with
	       the same	name as	the current machine type and architecture, in
	       every directory which it	searches.  Machine specific areas are
	       checked before architecture specific areas, and architecture
	       specific	areas are checked before general areas.	 For example,
	       for "i386:pc98",	the following subdirectories will be searched
	       for section 8 manpages, in order: man8/pc98, man8/i386, and

	       The current machine type	may be overridden using	this option or
	       by setting the environment variable MACHINE to the name of a
	       specific	machine.  The current architecture may be overridden
	       using this option or by setting the environment variable
	       MACHINE_ARCH to the name	of a specific architecture.  This op-
	       tion overrides the MACHINE and MACHINE_ARCH environment vari-
	       ables.  A machine component, if omitted,	defaults to arch.

     -o	       Look for	original, non-localized	manpages only.

	       By default, man searches	for a localized	manpage	in a set of
	       locale subdirectories of	each manpath(1)	component.

	       Locale name is taken from the first of three environment	vari-
	       ables with a nonempty value: LC_ALL, LC_CTYPE, or LANG, in the
	       specified order.

	       If the value could not be determined, or	is not a valid locale
	       name, then only non-localized manpage will be looked up.

	       Otherwise, man will search in the following subdirectories, in
	       the order of precedence:


	       For example, for	the "de_DE.ISO8859-1" locale, man will search
	       in the following	subdirectories of the /usr/share/man manpath


	       Finally,	if the search of localized manpage fails, it will be
	       looked up in the	default	/usr/share/man directory.

     -p	string
	       Specify the sequence of preprocessors to	run before nroff(1) or
	       troff(1).  Not all installations	will have a full set of	pre-
	       processors.  Some of the	preprocessors and the letters used to
	       designate them are: eqn (e), grap (g), pic (p), tbl (t),	vgrind
	       (v), refer (r).	This option overrides the MANROFFSEQ environ-
	       ment variable.

     -t	       Use "/usr/bin/groff -S -man" to format the manual page, passing
	       the output to stdout.  The default output format	of groff(1) is
	       Postscript, but see the manual page of groff(1) for ways	to
	       pick an alternate format.

	       Depending on the	selected format	and the	availability of	print-
	       ing devices, the	output may need	to be passed through some fil-
	       ter or another before being printed.

     -w	       Do not actually display the man pages, but do print the loca-
	       tion(s) of the files that would be formatted or displayed.

		   These variables specify the preferred language for manual
		   pages.  (See	the -o option above.)

     MACHINE	   If MACHINE is set, its value	is used	to override the	cur-
		   rent	machine	type when searching machine specific subdirec-

     MACHINE_ARCH  If MACHINE_ARCH is set, its value is	used to	override the
		   current architecture	when searching architecture specific

     MANPATH	   If MANPATH is set, its value	is used	as the path to search
		   for manual pages.

     MANROFFSEQ	   If MANROFFSEQ is set, its value is used to determine	the
		   set of preprocessors	run before running nroff(1) or
		   troff(1).  By default, pages	are passed through the table
		   preprocessor	(tbl(1)) before	nroff(1).

     MANSECT	   If MANSECT is set, its value	is used	to determine which
		   manual sections to search.

     PAGER	   If PAGER is set, its	value is used as the name of the pro-
		   gram	to use to display the man page.	 By default, "more -s"
		   is used.

     Normally, to look at the relevant manpage information for "getopt", one
     would use:

	   man getopt

     However, when referring to	a specific section of the manual, such as
     getopt(3),	one would use:

	   man 3 getopt

     apropos(1), groff(1), manpath(1), more(1),	whatis(1), man(7), mdoc(7)

     The -t option only	works if the troff(1)-like program is installed.
