man [-?V]
man is the system's manual pager. Each page argument given to man is
normally the name of a program, utility or function. The manual page
associated with each of these arguments is then found and displayed.
A section, if provided, will direct man to look only in that section
of the manual. The default action is to search in all of the
available sections following a pre-defined order ("1 n l 8 3 0 2 5 4
9 6 7" by default, unless overridden by the SECTION directive in
/usr/local/etc/man_db.conf), and to show only the first page found,
even if page exists in several sections.
The table below shows the section numbers of the manual followed by
the types of pages they contain.
1 Executable programs or shell commands
2 System calls (functions provided by the kernel)
3 Library calls (functions within program libraries)
4 Special files (usually found in /dev)
5 File formats and conventions eg /etc/passwd
6 Games
7 Miscellaneous (including macro packages and conventions), e.g.
man(7), groff(7)
8 System administration commands (usually only for root)
9 Kernel routines [Non standard]
A manual page consists of several sections.
Conventional section names include NAME, SYNOPSIS, CONFIGURATION,
DESCRIPTION, OPTIONS, EXIT STATUS, RETURN VALUE, ERRORS, ENVIRONMENT,
FILES, VERSIONS, CONFORMING TO, NOTES, BUGS, EXAMPLE, AUTHORS, and
SEE ALSO.
The following conventions apply to the SYNOPSIS section and can be
used as a guide in other sections.
bold text type exactly as shown.
italic text replace with appropriate argument.
[-abc] any or all arguments within [ ] are optional.
-a|-b options delimited by | cannot be used together.
argument ... argument is repeatable.
[expression] ... entire expression within [ ] is repeatable.
Exact rendering may vary depending on the output device. For
instance, man will usually not be able to render italics when running
in a terminal, and will typically use underlined or coloured text
instead.
The command or function illustration is a pattern that should match
all possible invocations. In some cases it is advisable to
illustrate several exclusive invocations as is shown in the SYNOPSIS
section of this manual page.
man ls
Display the manual page for the item (program) ls.
man man.7
Display the manual page for macro package man from section 7.
man -a intro
Display, in succession, all of the available intro manual pages
contained within the manual. It is possible to quit between
successive displays or skip any of them.
man -t alias | lpr -Pps
Format the manual page referenced by `alias', usually a shell
manual page, into the default troff or groff format and pipe it
to the printer named ps. The default output for groff is usually
PostScript. man --help should advise as to which processor is
bound to the -t option.
man -l -Tdvi ./foo.1x.gz > ./foo.1x.dvi
This command will decompress and format the nroff source manual
page ./foo.1x.gz into a device independent (dvi) file. The
redirection is necessary as the -T flag causes output to be
directed to stdout with no pager. The output could be viewed
with a program such as xdvi or further processed into PostScript
using a program such as dvips.
man -k printf
Search the short descriptions and manual page names for the
keyword printf as regular expression. Print out any matches.
Equivalent to apropos printf.
man -f smail
Lookup the manual pages referenced by smail and print out the
short descriptions of any found. Equivalent to whatis smail.
Many options are available to man in order to give as much
flexibility as possible to the user. Changes can be made to the
search path, section order, output processor, and other behaviours
and operations detailed below.
If set, various environment variables are interrogated to determine
the operation of man. It is possible to set the `catch all' variable
$MANOPT to any string in command line format with the exception that
any spaces used as part of an option's argument must be escaped
(preceded by a backslash). man will parse $MANOPT prior to parsing
its own command line. Those options requiring an argument will be
overridden by the same options found on the command line. To reset
all of the options set in $MANOPT, -D can be specified as the initial
command line option. This will allow man to `forget' about the
options specified in $MANOPT although they must still have been
valid.
The manual pager utilities packaged as man-db make extensive use of
index database caches. These caches contain information such as
where each manual page can be found on the filesystem and what its
whatis (short one line description of the man page) contains, and
allow man to run faster than if it had to search the filesystem each
time to find the appropriate manual page. If requested using the -u
option, man will ensure that the caches remain consistent, which can
obviate the need to manually run software to update traditional
whatis text databases.
If man cannot find a mandb initiated index database for a particular
manual page hierarchy, it will still search for the requested manual
pages, although file globbing will be necessary to search within that
hierarchy. If whatis or apropos fails to find an index it will try
to extract information from a traditional whatis database instead.
These utilities support compressed source nroff files having, by
default, the extensions of .Z, .z and .gz. It is possible to deal
with any compression extension, but this information must be known at
compile time. Also, by default, any cat pages produced are
compressed using gzip. Each `global' manual page hierarchy such as
/usr/share/man or /usr/X11R6/man may have any directory as its cat
page hierarchy. Traditionally the cat pages are stored under the
same hierarchy as the man pages, but for reasons such as those
specified in the File Hierarchy Standard (FHS), it may be better to
store them elsewhere. For details on how to do this, please read
manpath(5). For details on why to do this, read the standard.
International support is available with this package. Native
language manual pages are accessible (if available on your system)
via use of locale functions. To activate such support, it is
necessary to set either $LC_MESSAGES, $LANG or another system
dependent environment variable to your language locale, usually
specified in the POSIX 1003.1 based format:
<language>[_<territory>[.<character-set>[,<version>]]]
If the desired page is available in your locale, it will be displayed
in lieu of the standard (usually American English) page.
Support for international message catalogues is also featured in this
package and can be activated in the same way, again if available. If
you find that the manual pages and message catalogues supplied with
this package are not available in your native language and you would
like to supply them, please contact the maintainer who will be
coordinating such activity.
For information regarding other features and extensions available
with this manual pager, please read the documents supplied with the
package.
man will search for the desired manual pages within the index
database caches. If the -u option is given, a cache consistency check
is performed to ensure the databases accurately reflect the
filesystem. If this option is always given, it is not generally
necessary to run mandb after the caches are initially created, unless
a cache becomes corrupt. However, the cache consistency check can be
slow on systems with many manual pages installed, so it is not
performed by default, and system administrators may wish to run mandb
every week or so to keep the database caches fresh. To forestall
problems caused by outdated caches, man will fall back to file
globbing if a cache lookup fails, just as it would if no cache was
present.
Once a manual page has been located, a check is performed to find out
if a relative preformatted `cat' file already exists and is newer
than the nroff file. If it does and is, this preformatted file is
(usually) decompressed and then displayed, via use of a pager. The
pager can be specified in a number of ways, or else will fall back to
a default is used (see option -P for details). If no cat is found or
is older than the nroff file, the nroff is filtered through various
programs and is shown immediately.
If a cat file can be produced (a relative cat directory exists and
has appropriate permissions), man will compress and store the cat
file in the background.
The filters are deciphered by a number of means. Firstly, the
command line option -p or the environment variable $MANROFFSEQ is
interrogated. If -p was not used and the environment variable was
not set, the initial line of the nroff file is parsed for a
preprocessor string. To contain a valid preprocessor string, the
first line must resemble
'\" <string>
where string can be any combination of letters described by option -p
below.
If none of the above methods provide any filter information, a
default set is used.
A formatting pipeline is formed from the filters and the primary
formatter (nroff or [tg]roff with -t) and executed. Alternatively,
if an executable program mandb_nfmt (or mandb_tfmt with -t) exists in
the man tree root, it is executed instead. It gets passed the manual
source file, the preprocessor string, and optionally the device
specified with -T or -E as arguments.
Non argument options that are duplicated either on the command line,
in $MANOPT, or both, are not harmful. For options that require an
argument, each duplication will override the previous argument value.
General options
-C file, --config-file=file
Use this user configuration file rather than the default of
~/.manpath.
-d, --debug
Print debugging information.
-D, --default
This option is normally issued as the very first option and
resets man's behaviour to its default. Its use is to reset
those options that may have been set in $MANOPT. Any options
that follow -D will have their usual effect.
--warnings[=warnings]
Enable warnings from groff. This may be used to perform
sanity checks on the source text of manual pages. warnings is
a comma-separated list of warning names; if it is not
supplied, the default is "mac". See the “Warnings” node in
info groff for a list of available warning names.
Main modes of operation
-f, --whatis
Equivalent to whatis. Display a short description from the
manual page, if available. See whatis(1) for details.
-k, --apropos
Equivalent to apropos. Search the short manual page
descriptions for keywords and display any matches. See
apropos(1) for details.
-K, --global-apropos
Search for text in all manual pages. This is a brute-force
search, and is likely to take some time; if you can, you
should specify a section to reduce the number of pages that
need to be searched. Search terms may be simple strings (the
default), or regular expressions if the --regex option is
used.
Note that this searches the sources of the manual pages, not
the rendered text, and so may include false positives due to
things like comments in source files. Searching the rendered
text would be much slower.
-l, --local-file
Activate `local' mode. Format and display local manual files
instead of searching through the system's manual collection.
Each manual page argument will be interpreted as an nroff
source file in the correct format. No cat file is produced.
If '-' is listed as one of the arguments, input will be taken
from stdin. When this option is not used, and man fails to
find the page required, before displaying the error message,
it attempts to act as if this option was supplied, using the
name as a filename and looking for an exact match.
-w, --where, --path, --location
Don't actually display the manual pages, but do print the
location(s) of the source nroff files that would be formatted.
-W, --where-cat, --location-cat
Don't actually display the manual pages, but do print the
location(s) of the cat files that would be displayed. If -w
and -W are both specified, print both separated by a space.
-c, --catman
This option is not for general use and should only be used by
the catman program.
-R encoding, --recode=encoding
Instead of formatting the manual page in the usual way, output
its source converted to the specified encoding. If you
already know the encoding of the source file, you can also use
manconv(1) directly. However, this option allows you to
convert several manual pages to a single encoding without
having to explicitly state the encoding of each, provided that
they were already installed in a structure similar to a manual
page hierarchy.
Finding manual pages
-L locale, --locale=locale
man will normally determine your current locale by a call to
the C function setlocale(3) which interrogates various
environment variables, possibly including $LC_MESSAGES and
$LANG. To temporarily override the determined value, use this
option to supply a locale string directly to man. Note that
it will not take effect until the search for pages actually
begins. Output such as the help message will always be
displayed in the initially determined locale.
-m system[,...], --systems=system[,...]
If this system has access to other operating system's manual
pages, they can be accessed using this option. To search for
a manual page from NewOS's manual page collection, use the
option -m NewOS.
The system specified can be a combination of comma delimited
operating system names. To include a search of the native
operating system's manual pages, include the system name man
in the argument string. This option will override the $SYSTEM
environment variable.
-M path, --manpath=path
Specify an alternate manpath to use. By default, man uses
manpath derived code to determine the path to search. This
option overrides the $MANPATH environment variable and causes
option -m to be ignored.
A path specified as a manpath must be the root of a manual
page hierarchy structured into sections as described in the
man-db manual (under "The manual page system"). To view
manual pages outside such hierarchies, see the -l option.
-S list, -s list, --sections=list
List is a colon- or comma-separated list of `order specific'
manual sections to search. This option overrides the $MANSECT
environment variable. (The -s spelling is for compatibility
with System V.)
-e sub-extension, --extension=sub-extension
Some systems incorporate large packages of manual pages, such
as those that accompany the Tcl package, into the main manual
page hierarchy. To get around the problem of having two
manual pages with the same name such as exit(3), the Tcl pages
were usually all assigned to section l. As this is
unfortunate, it is now possible to put the pages in the
correct section, and to assign a specific `extension' to them,
in this case, exit(3tcl). Under normal operation, man will
display exit(3) in preference to exit(3tcl). To negotiate
this situation and to avoid having to know which section the
page you require resides in, it is now possible to give man a
sub-extension string indicating which package the page must
belong to. Using the above example, supplying the option
-e tcl to man will restrict the search to pages having an
extension of *tcl.
-i, --ignore-case
Ignore case when searching for manual pages. This is the
default.
-I, --match-case
Search for manual pages case-sensitively.
--regex
Show all pages with any part of either their names or their
descriptions matching each page argument as a regular
expression, as with apropos(1). Since there is usually no
reasonable way to pick a "best" page when searching for a
regular expression, this option implies -a.
--wildcard
Show all pages with any part of either their names or their
descriptions matching each page argument using shell-style
wildcards, as with apropos(1) --wildcard. The page argument
must match the entire name or description, or match on word
boundaries in the description. Since there is usually no
reasonable way to pick a "best" page when searching for a
wildcard, this option implies -a.
--names-only
If the --regex or --wildcard option is used, match only page
names, not page descriptions, as with whatis(1). Otherwise,
no effect.
-a, --all
By default, man will exit after displaying the most suitable
manual page it finds. Using this option forces man to display
all the manual pages with names that match the search
criteria.
-u, --update
This option causes man to perform an `inode level' consistency
check on its database caches to ensure that they are an
accurate representation of the filesystem. It will only have
a useful effect if man is installed with the setuid bit set.
--no-subpages
By default, man will try to interpret pairs of manual page
names given on the command line as equivalent to a single
manual page name containing a hyphen or an underscore. This
supports the common pattern of programs that implement a
number of subcommands, allowing them to provide manual pages
for each that can be accessed using similar syntax as would be
used to invoke the subcommands themselves. For example:
$ man -aw git diff
/usr/share/man/man1/git-diff.1.gz
To disable this behaviour, use the --no-subpages option.
$ man -aw --no-subpages git diff
/usr/share/man/man1/git.1.gz
/usr/share/man/man3/Git.3pm.gz
/usr/share/man/man1/diff.1.gz
Controlling formatted output
-P pager, --pager=pager
Specify which output pager to use. By default, man uses less.
This option overrides the $MANPAGER environment variable,
which in turn overrides the $PAGER environment variable. It
is not used in conjunction with -f or -k.
The value may be a simple command name or a command with
arguments, and may use shell quoting (backslashes, single
quotes, or double quotes). It may not use pipes to connect
multiple commands; if you need that, use a wrapper script,
which may take the file to display either as an argument or on
standard input.
-r prompt, --prompt=prompt
If a recent version of less is used as the pager, man will
attempt to set its prompt and some sensible options. The
default prompt looks like
Manual page name(sec) line x
where name denotes the manual page name, sec denotes the
section it was found under and x the current line number.
This is achieved by using the $LESS environment variable.
Supplying -r with a string will override this default. The
string may contain the text $MAN_PN which will be expanded to
the name of the current manual page and its section name
surrounded by `(' and `)'. The string used to produce the
default could be expressed as
\ Manual\ page\ \$MAN_PN\ ?ltline\ %lt?L/%L.:
byte\ %bB?s/%s..?\ (END):?pB\ %pB\\%..
(press h for help or q to quit)
It is broken into three lines here for the sake of readability
only. For its meaning see the less(1) manual page. The
prompt string is first evaluated by the shell. All double
quotes, back-quotes and backslashes in the prompt must be
escaped by a preceding backslash. The prompt string may end
in an escaped $ which may be followed by further options for
less. By default man sets the -ix8 options.
The $MANLESS environment variable described below may be used
to set a default prompt string if none is supplied on the
command line.
-7, --ascii
When viewing a pure ascii(7) manual page on a 7 bit terminal
or terminal emulator, some characters may not display
correctly when using the latin1(7) device description with GNU
nroff. This option allows pure ascii manual pages to be
displayed in ascii with the latin1 device. It will not
translate any latin1 text. The following table shows the
translations performed: some parts of it may only be displayed
properly when using GNU nroff's latin1(7) device.
Description Octal latin1 ascii
────────────────────────────────────────
continuation 255 ‐ -
hyphen
bullet (middle 267 · o
dot)
acute accent 264 ´ '
multiplication 327 × x
sign
If the latin1 column displays correctly, your terminal may be
set up for latin1 characters and this option is not necessary.
If the latin1 and ascii columns are identical, you are reading
this page using this option or man did not format this page
using the latin1 device description. If the latin1 column is
missing or corrupt, you may need to view manual pages with
this option.
This option is ignored when using options -t, -H, -T, or -Z
and may be useless for nroff other than GNU's.
-E encoding, --encoding=encoding
Generate output for a character encoding other than the
default. For backward compatibility, encoding may be an nroff
device such as ascii, latin1, or utf8 as well as a true
character encoding such as UTF-8.
--no-hyphenation, --nh
Normally, nroff will automatically hyphenate text at line
breaks even in words that do not contain hyphens, if it is
necessary to do so to lay out words on a line without
excessive spacing. This option disables automatic
hyphenation, so words will only be hyphenated if they already
contain hyphens.
If you are writing a manual page and simply want to prevent
nroff from hyphenating a word at an inappropriate point, do
not use this option, but consult the nroff documentation
instead; for instance, you can put "\%" inside a word to
indicate that it may be hyphenated at that point, or put "\%"
at the start of a word to prevent it from being hyphenated.
--no-justification, --nj
Normally, nroff will automatically justify text to both
margins. This option disables full justification, leaving
justified only to the left margin, sometimes called "ragged-
right" text.
If you are writing a manual page and simply want to prevent
nroff from justifying certain paragraphs, do not use this
option, but consult the nroff documentation instead; for
instance, you can use the ".na", ".nf", ".fi", and ".ad"
requests to temporarily disable adjusting and filling.
-p string, --preprocessor=string
Specify the sequence of preprocessors to run before nroff or
troff/groff. Not all installations will have a full set of
preprocessors. 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
environment variable. zsoelim is always run as the very first
preprocessor.
-t, --troff
Use groff -mandoc to format the manual page to stdout. This
option is not required in conjunction with -H, -T, or -Z.
-T[device], --troff-device[=device]
This option is used to change groff (or possibly troff's)
output to be suitable for a device other than the default. It
implies -t. Examples (provided with Groff-1.17) include dvi,
latin1, ps, utf8, X75 and X100.
-H[browser], --html[=browser]
This option will cause groff to produce HTML output, and will
display that output in a web browser. The choice of browser
is determined by the optional browser argument if one is
provided, by the $BROWSER environment variable, or by a
compile-time default if that is unset (usually lynx). This
option implies -t, and will only work with GNU troff.
-X[dpi], --gxditview[=dpi]
This option displays the output of groff in a graphical window
using the gxditview program. The dpi (dots per inch) may be
75, 75-12, 100, or 100-12, defaulting to 75; the -12 variants
use a 12-point base font. This option implies -T with the
X75, X75-12, X100, or X100-12 device respectively.
-Z, --ditroff
groff will run troff and then use an appropriate post-
processor to produce output suitable for the chosen device.
If groff -mandoc is groff, this option is passed to groff and
will suppress the use of a post-processor. It implies -t.
Getting help
-?, --help
Print a help message and exit.
--usage
Print a short usage message and exit.
-V, --version
Display version information.
0 Successful program execution.
1 Usage, syntax or configuration file error.
2 Operational error.
3 A child process returned a non-zero exit status.
16 At least one of the pages/files/keywords didn't exist or
wasn't matched.
MANPATH
If $MANPATH is set, its value is used as the path to search
for manual pages.
MANROFFOPT
The contents of $MANROFFOPT are added to the command line
every time man invokes the formatter (nroff, troff, or groff).
MANROFFSEQ
If $MANROFFSEQ is set, its value is used to determine the set
of preprocessors to pass each manual page through. The
default preprocessor list is system dependent.
MANSECT
If $MANSECT is set, its value is a colon-delimited list of
sections and it is used to determine which manual sections to
search and in what order. The default is "1 n l 8 3 0 2 5 4 9
6 7", unless overridden by the SECTION directive in
/usr/local/etc/man_db.conf.
MANPAGER, PAGER
If $MANPAGER or $PAGER is set ($MANPAGER is used in
preference), its value is used as the name of the program used
to display the manual page. By default, less is used.
The value may be a simple command name or a command with
arguments, and may use shell quoting (backslashes, single
quotes, or double quotes). It may not use pipes to connect
multiple commands; if you need that, use a wrapper script,
which may take the file to display either as an argument or on
standard input.
MANLESS
If $MANLESS is set, its value will be used as the default
prompt string for the less pager, as if it had been passed
using the -r option (so any occurrences of the text $MAN_PN
will be expanded in the same way). For example, if you want
to set the prompt string unconditionally to “my prompt
string”, set $MANLESS to ‘-Psmy prompt string’. Using the -r
option overrides this environment variable.
BROWSER
If $BROWSER is set, its value is a colon-delimited list of
commands, each of which in turn is used to try to start a web
browser for man --html. In each command, %s is replaced by a
filename containing the HTML output from groff, %% is replaced
by a single percent sign (%), and %c is replaced by a colon
(:).
SYSTEM If $SYSTEM is set, it will have the same effect as if it had
been specified as the argument to the -m option.
MANOPT If $MANOPT is set, it will be parsed prior to man's command
line and is expected to be in a similar format. As all of the
other man specific environment variables can be expressed as
command line options, and are thus candidates for being
included in $MANOPT it is expected that they will become
obsolete. N.B. All spaces that should be interpreted as part
of an option's argument must be escaped.
MANWIDTH
If $MANWIDTH is set, its value is used as the line length for
which manual pages should be formatted. If it is not set,
manual pages will be formatted with a line length appropriate
to the current terminal (using the value of $COLUMNS, an
ioctl(2) if available, or falling back to 80 characters if
neither is available). Cat pages will only be saved when the
default formatting can be used, that is when the terminal line
length is between 66 and 80 characters.
MAN_KEEP_FORMATTING
Normally, when output is not being directed to a terminal
(such as to a file or a pipe), formatting characters are
discarded to make it easier to read the result without special
tools. However, if $MAN_KEEP_FORMATTING is set to any non-
empty value, these formatting characters are retained. This
may be useful for wrappers around man that can interpret
formatting characters.
MAN_KEEP_STDERR
Normally, when output is being directed to a terminal (usually
to a pager), any error output from the command used to produce
formatted versions of manual pages is discarded to avoid
interfering with the pager's display. Programs such as groff
often produce relatively minor error messages about
typographical problems such as poor alignment, which are
unsightly and generally confusing when displayed along with
the manual page. However, some users want to see them anyway,
so, if $MAN_KEEP_STDERR is set to any non-empty value, error
output will be displayed as usual.
LANG, LC_MESSAGES
Depending on system and implementation, either or both of
$LANG and $LC_MESSAGES will be interrogated for the current
message locale. man will display its messages in that locale
(if available). See setlocale(3) for precise details.
