NAME
     man -- display online manual documentation	pages

SYNOPSIS
     man [-adho] [-t | -w] [-M manpath]	[-P pager] [-S mansect]
	 [-m arch[:machine]] [-p [eprtv]] [mansect] page ...
     man -f keyword ...
     man -k keyword ...

DESCRIPTION
     The man utility finds and displays	online manual documentation pages.  If
     mansect is	provided, man restricts	the search to the specific section of
     the manual.

     Options that man understands:

     -M	manpath
	     Forces a specific colon separated manual path instead of the de-
	     fault search path.	 See manpath(1).  Overrides the	MANPATH	envi-
	     ronment variable.

     -P	pager
	     Use specified pager.  Defaults to "less -sR" if color support is
	     enabled, or "more -s".  Overrides the MANPAGER environment	vari-
	     able, which in turn overrides the PAGER environment variable.

     -S	mansect
	     Restricts manual sections searched	to the specified colon delim-
	     ited list.	 Defaults to "1:8:2:3:n:4:5:6:7:9:l".  Overrides the
	     MANSECT environment variable.

     -a	     Display all manual	pages instead of just the first	found for each
	     page argument.

     -d	     Print extra debugging information.	 Repeat	for increased ver-
	     bosity.  Does not display the manual page.

     -f	     Emulate whatis(1).

     -h	     Display short help	message	and exit.

     -k	     Emulate apropos(1).

     -m	arch[:machine]
	     Override the default architecture and machine settings allowing
	     lookup of other platform specific manual pages.  See
	     IMPLEMENTATION NOTES for how this option changes the default be-
	     havior.  Overrides	the MACHINE_ARCH and MACHINE environment vari-
	     ables.

     -o	     Force use of non-localized	manual pages.  See IMPLEMENTATION
	     NOTES for how locale specific searches work.  Overrides the
	     LC_ALL, LC_CTYPE, and LANG	environment variables.

     -p	[eprtv]
	     Use the list of given preprocessors before	running	nroff(1) or
	     troff(1).	Valid preprocessors arguments:

	     e	     eqn(1)
	     p	     pic(1)
	     r	     refer(1)
	     t	     tbl(1)
	     v	     vgrind(1)

	     Overrides the MANROFFSEQ environment variable.

     -t	     Send manual page source through troff(1) allowing transformation
	     of	the manual pages to other formats.

     -w	     Display the location of the manual	page instead of	the contents
	     of	the manual page.

IMPLEMENTATION NOTES
   Locale Specific Searches
     The man utility supports manual pages in different	locales.  The search
     behavior is dictated by the first of three	environment variables with a
     nonempty string: LC_ALL, LC_CTYPE,	or LANG.  If set, man will search for
     locale specific manual pages using	the following logic:

	   lang_country.charset
	   lang.charset
	   en.charset

     For example, if LC_ALL is set to "ja_JP.eucJP", man will search the fol-
     lowing paths when considering section 1 manual pages in /usr/share/man:

	   /usr/share/man/ja_JP.eucJP/man1
	   /usr/share/man/ja.eucJP/man1
	   /usr/share/man/en.eucJP/man1
	   /usr/share/man/man1

   Platform Specific Searches
     The man utility supports platform specific	manual pages.  The search be-
     havior is dictated	by the -m option or the	MACHINE_ARCH and MACHINE envi-
     ronment variables.	 For example, if MACHINE_ARCH is set to	"i386" and
     MACHINE is	set to "pc98", man will	search the following paths when	con-
     sidering section 4	manual pages in	/usr/share/man:

	   /usr/share/man/man4/pc98
	   /usr/share/man/man4/i386
	   /usr/share/man/man4

   Displaying Specific Manual Files
     The man utility also supports displaying a	specific manual	page if	passed
     a path to the file	as long	as it contains a `/' character.

ENVIRONMENT
     The following environment variables affect	the execution of man:

     LC_ALL, LC_CTYPE, LANG
		 Used to find locale specific manual pages.  Valid values can
		 be found by running the locale(1) command.  See
		 IMPLEMENTATION	NOTES for details.  Influenced by the -o op-
		 tion.

     MACHINE_ARCH, MACHINE
		 Used to find platform specific	manual pages.  If unset, the
		 output	of "sysctl hw.machine_arch" and	"sysctl	hw.machine" is
		 used respectively.  See IMPLEMENTATION	NOTES for details.
		 Corresponds to	the -m option.

     MANPATH	 Used to find the location of the manual files.	 See
		 manpath(1) for	additional information.	 Corresponds to	the -M
		 option.

     MANROFFSEQ	 Used to determine the preprocessors for the manual source be-
		 fore running nroff(1) or troff(1).  If	unset, defaults	to
		 tbl(1).  Corresponds to the -p	option.

     MANSECT	 Restricts manual sections searched to the specified colon de-
		 limited list.	Corresponds to the -S option.

     MANWIDTH	 If set	to a numeric value, used as the	width manpages should
		 be displayed.	Otherwise, if set to a special value "tty",
		 and output is to a terminal, the pages	may be displayed over
		 the whole width of the	screen.

     MANCOLOR	 If set, enables color support.

     MANPAGER	 Program used to display files.

		 If unset, and color support is	enabled, "less -sR" is used.

		 If unset, and color support is	disabled, then PAGER is	used.
		 If that has no	value either, "more -s"	is used.

FILES
     /etc/man.conf
	     System configuration file.
     /usr/local/etc/man.d/*.conf
	     Local configuration files.
