[mansect] page ... |
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.
The sections of the manual are:
- FreeBSD General Commands Manual
- FreeBSD System Calls Manual
- FreeBSD Library Functions Manual
- FreeBSD Kernel Interfaces Manual
- FreeBSD File Formats Manual
- FreeBSD Games Manual
- FreeBSD Miscellaneous Information Manual
- FreeBSD System Manager's Manual
- FreeBSD Kernel Developer's Manual
Options that man understands:
-M
manpath
- Forces a specific colon separated manual path instead of the default
search path. See
manpath(1).
Overrides the
MANPATH environment variable.
-P
pager
- Use specified pager. Defaults to “
less
-sR ” if color support is enabled, or
“less -s ”. Overrides the
MANPAGER environment variable, which in turn
overrides the PAGER environment variable.
-S
mansect
- Restricts manual sections searched to the specified colon delimited list.
Defaults to
“
1:8:2:3:3lua: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 verbosity. 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 behavior. Overrides the
MACHINE_ARCH and MACHINE
environment variables.
-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.
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 following 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
The man utility supports platform specific manual pages.
The search behavior is dictated by the -m option or
the MACHINE_ARCH and MACHINE
environment variables. For example, if MACHINE_ARCH is
set to “aarch64 ” and
MACHINE is set to
“arm64 ”, man
will search the following paths when considering section 4 manual pages in
/usr/share/man:
- /usr/share/man/man4/aarch64
- /usr/share/man/man4/arm64
- /usr/share/man/man4
The man utility also supports displaying a specific
manual page if passed a path to the file as long as it contains a
‘/ ’ character.
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
option.
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
- The standard search path used by
man(1)
may be changed by specifying a path in the
MANPATH
environment variable. Invalid paths, or paths without manual databases,
are ignored. Overridden by -M . If
MANPATH begins with a colon, it is appended to the
default list; if it ends with a colon, it is prepended to the default
list; or if it contains two adjacent colons, the standard search path is
inserted between the colons. If none of these conditions are met, it
overrides the standard search path.
MANROFFSEQ
- Used to determine the preprocessors for the manual source before 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 delimited 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.
- 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,
“less -s ” is used.
- /etc/man.conf
- System configuration file.
- /usr/local/etc/man.d/*.conf
- Local configuration files.
The man utility exits 0 on success,
and >0 if an error occurs.
