.SH BESKRIVELSE
\fBman\fP er systemets manuelle tekstviser. Hver \fIside\fP\-parameter sendt til
\fBman\fP er normalt navnet på et program, et redskab eller en
funktion. \fImanualsiden\fP associeret med hvert af disse parametre findes så
og vises. \fIafsnit\fP, hvis angivet, vil dirigere \fB%man\fP til kun at kigge i
det \fIafsnit\fP af manualen. Standardhandlingen er at søge i alle de
tilgængelige \fIafsnit\fP, der efterfølger den prædefinerede rækkefølge
("1 n l 8 3 2 3posix 3pm 3perl 3am 5 4 9 6 7" som standard, med mindre overskrevet af direktivet \fBSECTION\fP
i \fI/etc/manpath.config\fP), og at vise kun den første \fIside\fP fundet, selv
hvis \fIside\fP findes i flere \fIafsnit\fP.

Tabellen nedenfor viser \fIsection\fP\-antallet af manualen efterfulgt af typen
af sider de indeholder.

Præcis optegning kan afhænge af uddataenheden. For eksempel vil man normalt
ikke kunne optegne kursiv når man befinder sig i en manual, og man vil
normalt bruge understregning eller farvelagt tekst i stedet for.

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 \fBSYNOPSIS\fP section of this manual
page.
.SH EKSEMPLER
.TP  \w'man\ 'u
\fBman\fP\fI\ ls\fP
Vis manualsiden for \fIpunkt\fP (program) \fIls\fP.
.TP 
\fBman \fP\fIman\fP.\fI7\fP
Vis manualsiden for makropakken \fIman\fP fra afsnit \fI7\fP.
.TP 
\fBman\ \-a\fP\fI\ intro\fP
Vis, i rækkefølge, alle de tilgængelige \fIintro\fP\-manualsider indeholdt i
denne manual. Det er muligt at afbryde mellem successive visninger eller
udelade nogle af dem.
.TP 
\fBman \-t \fP\fIalias \fP|\fI lpr \-Pps\fP
Format the manual page referenced by `\fIalias\fP', usually a shell manual
page, into the default \fBtroff\fP or \fBgroff\fP format and pipe it to the
printer named \fIps\fP.  The default output for \fBgroff\fP is usually
PostScript.  \fBman \-\-help\fP should advise as to which processor is bound to
the \fB\-t\fP option.
.TP 
\fBman \-l \-T\fP\fIdvi ./foo.1x.gz\fP\fB > \fP\fI./foo.1x.dvi\fP
This command will decompress and format the nroff source manual page
\&\fI./foo.1x.gz\fP into a \fBdevice independent (dvi)\fP file.  The redirection is
necessary as the \fB\-T\fP flag causes output to be directed to \fBstdout\fP with
no pager.  The output could be viewed with a program such as \fBxdvi\fP or
further processed into PostScript using a program such as \fBdvips.\fP
.TP 
\fBman\ \-k\fP\fI\ printf\fP
Søg i de korte beskrivelser og navnene på manualsiderne for nøgleordet
\fIprintf\fP som regulært udtryk. Udskriv resultaterne. Svarer til
\fBapropos\fP\fI\ printf\fP\fB.\fP
.TP 
\fBman\ \-f\fP\fI\ smail\fP
Slå manualsiderne refereret af \fIsmail\fP op og vis den korte beskrivelse for
det fundne resultat. Svarer til \fBwhatis\fP\fI\ smail\fP\fB.\fP
.SH OVERBLIK
Mange tilvalg er tilgængelige for \fBman\fP for at give så meget
fleksibilitet som muligt for slutbrugeren. Ændringer kan ske for søgestien,
afsnitrækkefølge, uddataprocessor og anden opførsel og operationer
detaljeret nedenfor.

Hvis angivet, bliver diverse miljøvariabler forhandlet for at bestemme
operationen af \fBman\fP. Det er muligt at angive variablen »catch all«
$\fBMANOPT\fP til enhver streng i kommandolinjeformat med den undtagelse at
eventuelle mellemrum brugt som del af et tilvalgs argument skal have
undvigesekvens (forudstillet med en skråstreg). \fBman\fP vil fortolke
$\fBMANOPT\fP før fortolkning af sin egen kommandolinje. Disse tilvalg der
kræver et argument vil blive overskrevet af de samme tilvalg fundet på
kommandolinjen. For at nulstille hele tilvalgssættet i $\fBMANOPT\fP, \fB\-D\fP kan
specificeres som opstartsindstilling for kommandolinjen. Dette vil tillade
man at »glemme« tilvalgene specificeret i $\fBMANOPT\fP selvom de stadig må
have været gyldige..

The manual pager utilities packaged as \fBman\-db\fP make extensive use of
\fBindex\fP database caches.  These caches contain information such as where
each manual page can be found on the filesystem and what its \fIwhatis\fP
(short one line description of the man page) contains, and allow \fBman\fP to
run faster than if it had to search the filesystem each time to find the
appropriate manual page.  If requested using the \fB\-u\fP option, \fBman\fP will
ensure that the caches remain consistent, which can obviate the need to
manually run software to update traditional \fIwhatis\fP text databases.

.\"`User' manual page hierarchies will have
.\".B index
.\"caches created `on the fly'.
If \fBman\fP cannot find a \fBmandb\fP initiated \fBindex\fP 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 \fBwhatis\fP or \fBapropos\fP fails to find an \fBindex\fP it will
try to extract information from a traditional \fIwhatis\fP database instead.

These utilities support compressed source nroff files having, by default,
the extensions of \fB.Z\fP, \fB.z\fP and \fB.gz\fP.  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 \fBgzip\fP.  Each
`global' manual page hierarchy such as \fI/usr/share/man\fP or
\fI/usr/X11R6/man\fP 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 \fBFile Hierarchy
Standard (FHS)\fP, it may be better to store them elsewhere.  For details on
how to do this, please read \fBmanpath\fP(5).  For details on why to do this,
read the standard.

Oversættelser er tilgængelige via denne pakke. Oversatte manualsider kan
tilgås (hvis de er tilgængelige på dit system) via brug af
\fIsprog\fP\-funktioner. For at aktivere denne understøttelse, er det nødvendigt
at angive enten $\fBLC_MESSAGES\fP, $\fBLANG\fP eller en anden systemafhængig
miljøvariabel for dit sprog, normalt specificeret i det \fBPOSIX
1003.1\fP\-baserede format:

.\"
.\" Need a \c to make sure we don't get a space where we don't want one
.\"
<\fIlanguage\fP>[\|\fB_\fP<\fIterritory\fP>\|[\|\fB.\fP<\fItegnsæt\fP>\|[\|\fB,\fP<\fIversion\fP>\|]\|]\|]

Hvis den ønskede side er tilgængelig i dit \fIsprog\fP, vil den blive vist i
stedet for standardsiden (normalt amerikansk\-engelsk).

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 om andre funktioner og udvidelser tilgængelige med denne
manualtekstviser, så læs venligst dokumenterne leveret med denne pakke.
.SH STANDARDER
\fBman\fP will search for the desired manual pages within the \fIindex\fP
database caches. If the \fB\-u\fP 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 \fBmandb\fP
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 \fBmandb\fP every week or so to keep the
database caches fresh.  To forestall problems caused by outdated caches,
\fBman\fP 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
\fB\-P\fP 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), \fBman\fP will compress and store the cat file in
the background.

Filtrene tydes vis et antal metoder. Først tydes kommandolinjetilvalget
\fB\-p\fP eller miljøvariablen $\fBMANROFFSEQ\fP. Hvis \fB\-p\fP ikke blev brugt og
miljøvariablen ikke var angivet, så fortolkes opstartslinjen for nroff\-filen
for en forbrænderstrenge. For at indeholde en gyldig forbrænderstreng, så
skal den første linje ligne

\&\fB'\e"\fP <\fBstring\fP>

Hvor \fBstreng\fP kan være enhver kombination af bogstaver beskrevet af
tilvalget \fB\-p\fP nedenfor.

Hvis ingen af de ovenstående metoder giver filterinformation, så bruges et
standardsæt.

.\" ********************************************************************
A formatting pipeline is formed from the filters and the primary formatter
(\fBnroff\fP or [\fBtg\fP]\fBroff\fP with \fB\-t\fP)  and executed.  Alternatively, if an
executable program \fImandb_nfmt\fP (or \fImandb_tfmt\fP with \fB\-t\fP)  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
\fB\-T\fP or \fB\-E\fP as arguments.
.SH TILVALG
Tilvalg uden argumenter som dublikeres enten på kommandolinjen, i

.TP 
.if  !'po4a'hide' .BR \-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 \fB\-\-regex\fP option is
used.
.IP
Note that this searches the \fIsources\fP 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.

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

this option was supplied, using the name as a filename and looking for an
exact match.

\fBman\fP vil normalt bestemme dit lokale sprog med et kald til
C\-funktionen \fBsetlocale\fP(3), som undersøger diverse miljøvariabler,
muligvis inklusive $\fBLC_MESSAGES\fP og $\fBLANG\fP. For midlertidigt at
overskrive den afslørede værdi bruges dette tilvalg til at supplere en
\fIsprog\fP\-streng direkte til \fBman\fP. Bemærk at det ikke vil træde i
kraft før søgningen efter sider rent faktisk begynder. Resultatet såsom
hjælpebeskeden vil altid blive vist i det oprindeligt bestemte sprog.

Hvis dette system har adgang til andre operativsystemers manualsider, så kan
de tilgås med dette tilvalg. For at søge efter en manualside fra NytOS's
manualsidesamling bruges tilvalget \fB\-m\fP \fBNytOS\fP.

Det angivet \fIsystem\fP kan være en kombination af kommaadskilt
operativsystemnavne. For at inkludere en søgning i manualsiderne for
udgangspunktets operativsystem inkluderes systemnavnet \fBman\fP i
argumentstrengen. Dette tilvalg vil overskrive miljøvariablen $\fBSYSTEM\fP.

\fB\-M\ \fP\fIsti\fP,\ \fB\-\-manpath=\fP\fIsti\fP
Angiv en alternativ manualsti. Som standard bruger \fBman\fP
\fBmanpath\fP\-afledt kode til at bestemme søgestien. Dette tilvalg
overskriver miljøvariablen $\fBMANPATH\fP og medfører at tilvalget \fB\-m\fP
ignoreres.

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 \fB\-l\fP option.
.TP 
\fB\-S\ \fP\fIliste\fP,\ \fB\-s\ \fP\fIliste\fP,\ \fB\-\-sections=\fP\fIliste\fP
List is a colon\- or comma\-separated list of `order specific' manual sections

(The \fB\-s\fP spelling is for compatibility with System V.)
.TP 
\fB\-e\ \fP\fIsub\-extension\fP,\ \fB\-\-extension=\fP\fIsub\-extension\fP
Some systems incorporate large packages of manual pages, such as those that
accompany the \fBTcl\fP package, into the main manual page hierarchy.  To get
around the problem of having two manual pages with the same name such as
\fBexit\fP(3), the \fBTcl\fP pages were usually all assigned to section \fBl\fP.  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,
\fBexit\fP(3tcl).  Under normal operation, \fBman\fP will display \fBexit\fP(3)  in
preference to \fBexit\fP(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 \fBman\fP a \fIsub\-extension\fP string indicating which package
the page must belong to.  Using the above example, supplying the option
\fB\-e\ tcl\fP to \fBman\fP will restrict the search to pages having an extension
of \fB*tcl\fP.
.TP 
.if  !'po4a'hide' .BR \-i ", " \-\-ignore\-case

.TP 
.if  !'po4a'hide' .B \-\-regex
Show all pages with any part of either their names or their descriptions
matching each \fIpage\fP argument as a regular expression, as with
\fBapropos\fP(1).  Since there is usually no reasonable way to pick a "best"
page when searching for a regular expression, this option implies \fB\-a\fP.
.TP 
.if  !'po4a'hide' .B \-\-wildcard
Show all pages with any part of either their names or their descriptions
matching each \fIpage\fP argument using shell\-style wildcards, as with
\fBapropos\fP(1)  \fB\-\-wildcard\fP.  The \fIpage\fP 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 \fB\-a\fP.
.TP 
.if  !'po4a'hide' .B \-\-names\-only
Hvis enten tilvalget \fB\-\-regex\fP eller \fB\-\-wildcard\fP bruges, match kun
sidenavne, ikke sidebeskrivelser, som med \fBwhatis\fP(1). Ellers, ingen

.TP 
.if  !'po4a'hide' .BR \-a ", " \-\-all
Som standard vil \fBman\fP afslutte efter visning af den mest egnet

alle manualsiderne med navne som matcher søgekriteriet.
.TP 
.if  !'po4a'hide' .BR \-u ", " \-\-update
Dette tilvalg får \fBman\fP til at udføre en »inode level«\-konsistenskontrol
på dets databasemellemlager for at sikre at de er en præcis repræsentation

.TP 
.if  !'po4a'hide' .B \-\-no\-subpages
By default, \fBman\fP 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:

.nf
.if  !'po4a'hide' \&  $ man \-aw git diff
.if  !'po4a'hide' \&  /usr/share/man/man1/git\-diff.1.gz
.fi

For at deaktivere denne opførsel så brug tilvalget \fB\-\-no\-subpages\fP.

\fB\-P\ \fP\fItekstviser\fP,\ \fB\-\-pager=\fP\fItekstviser\fP
Specify which output pager to use.  By default, \fBman\fP uses \fBpager\fP,
falling back to \fBcat\fP if \fBpager\fP is not found or is not executable.
This option overrides the $\fBMANPAGER\fP environment variable, which in turn
overrides the $\fBPAGER\fP environment variable.  It is not used in conjunction
with \fB\-f\fP or \fB\-k\fP.

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.
.TP 
\fB\-r\ \fP\fIprompt\fP,\ \fB\-\-prompt=\fP\fIprompt\fP
Hvis en nylig version af \fBless\fP bruges som tekstsøger, så vil \fBman\fP
forsøge at angive den på sin prompt og vælge nogle fornuftige
tilvalg. Standardprompten ser således ud

\fB\ Manualside\fP\fI\ navn\fP\fB(\fP\fIsec\fP\fB)\fP\fB\ line\fP\fI\ x\fP

.\"The default options are
.\".BR \-six8 .
.\"The actual default will depend on your chosen
.\".BR locale .
hvor \fInavn\fP benvæner manualsidenavnet, \fIsektion\fP benævner sektionen den
blev fundet under og \fIx\fP det nuværende linjenummer. Dette opnås ved at
bruge miljøvariablen $\fBLESS\fP.

.\"You may need to do this if your
.\"version of
.\".B less
.\"rejects the default options or if you prefer a different prompt.
Supplying \fB\-r\fP with a string will override this default.  The string may
contain the text \fB$MAN_PN\fP 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

\fB\e\ Manual\e\ page\e\ \e$MAN_PN\e\ ?ltline\e\ %lt?L/%L.:\fP
.br
\fBbyte\e\ %bB?s/%s..?\e\ (END):?pB\e\ %pB\e\e%..\fP
.br
\fB(tryk h for hjælp eller q for afslut)\fP

It is broken into three lines here for the sake of readability only.  For
its meaning see the \fBless\fP(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 \fBman\fP sets the \fB\-ix8\fP options.

The $\fBMANLESS\fP environment variable described below may be used to set a
default prompt string if none is supplied on the command line.
.TP 
.if  !'po4a'hide' .BR \-7 ", " \-\-ascii
When viewing a pure \fIascii\fP(7)  manual page on a 7 bit terminal or terminal
emulator, some characters may not display correctly when using the
\fIlatin1\fP(7)  device description with \fBGNU\fP \fBnroff\fP.  This option allows
pure \fIascii\fP manual pages to be displayed in \fIascii\fP with the \fIlatin1\fP
device.  It will not translate any \fIlatin1\fP text.  The following table
shows the translations performed: some parts of it may only be displayed
properly when using \fBGNU\fP \fBnroff\fP's \fIlatin1\fP(7)  device.

If the \fIlatin1\fP column displays correctly, your terminal may be set up for
\fIlatin1\fP characters and this option is not necessary.  If the \fIlatin1\fP and
\fIascii\fP columns are identical, you are reading this page using this option
or \fBman\fP did not format this page using the \fIlatin1\fP device
description.  If the \fIlatin1\fP column is missing or corrupt, you may need to
view manual pages with this option.

This option is ignored when using options \fB\-t\fP, \fB\-H\fP, \fB\-T\fP, or \fB\-Z\fP and
may be useless for \fBnroff\fP other than \fBGNU's\fP.
.TP 
\fB\-E\ \fP\fIkodning\fP,\ \fB\-\-encoding\fP=\fIkodning\fP
Generate output for a character encoding other than the default.  For
backward compatibility, \fIencoding\fP may be an \fBnroff\fP device such as
\fBascii\fP, \fBlatin1\fP, or \fButf8\fP as well as a true character encoding such as
\fBUTF\-8\fP.
.TP 
.if  !'po4a'hide' .BR \-\-no\-hyphenation ", " \-\-nh
Normally, \fBnroff\fP 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 \fBnroff\fP from
hyphenating a word at an inappropriate point, do not use this option, but
consult the \fBnroff\fP documentation instead; for instance, you can put "\e%"
inside a word to indicate that it may be hyphenated at that point, or put
"\e%" at the start of a word to prevent it from being hyphenated.
.TP 
.if  !'po4a'hide' .BR \-\-no\-justification ", " \-\-nj
Normally, \fBnroff\fP 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 \fBnroff\fP from
justifying certain paragraphs, do not use this option, but consult the
\fBnroff\fP documentation instead; for instance, you can use the ".na", ".nf",
".fi", and ".ad" requests to temporarily disable adjusting and filling.
.TP 
\fB\-p\ \fP\fIstreng\fP,\ \fB\-\-preprocessor=\fP\fIstreng\fP
Specify the sequence of preprocessors to run before \fBnroff\fP or
\fBtroff\fP/\fBgroff\fP.  Not all installations will have a full set of
preprocessors.  Some of the preprocessors and the letters used to designate
them are: \fBeqn\fP (\fBe\fP), \fBgrap\fP (\fBg\fP), \fBpic\fP (\fBp\fP), \fBtbl\fP (\fBt\fP),
\fBvgrind\fP (\fBv\fP), \fBrefer\fP (\fBr\fP).  This option overrides the $\fBMANROFFSEQ\fP
environment variable.  \fBzsoelim\fP is always run as the very first
preprocessor.
.TP

.TP 
\fB\-H\fP[\fIbrowser\/\fP], \fB\-\-html\fP[=\fIbrowser\/\fP]
This option will cause \fBgroff\fP to produce HTML output, and will display
that output in a web browser.  The choice of browser is determined by the
optional \fIbrowser\fP argument if one is provided, by the $\fBBROWSER\fP
environment variable, or by a compile\-time default if that is unset (usually
\fBlynx\fP).  This option implies \fB\-t\fP, and will only work with \fBGNU\fP
\fBtroff\fP.
.TP 
\fB\-X\fP[\fIdpi\/\fP], \fB\-\-gxditview\fP[=\fIdpi\/\fP]
This option displays the output of \fBgroff\fP in a graphical window using the
\fBgxditview\fP program.  The \fIdpi\fP (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 \fB\-T\fP with the X75, X75\-12, X100, or X100\-12 device
respectively.

.if  !'po4a'hide' .B MANROFFOPT
The contents of $\fBMANROFFOPT\fP are added to the command line every time
\fBman\fP invokes the formatter (\fBnroff\fP, \fBtroff\fP, or \fBgroff\fP).
.TP 
.if  !'po4a'hide' .B MANROFFSEQ
If $\fBMANROFFSEQ\fP 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.
.TP 
.if  !'po4a'hide' .B MANSECT
If $\fBMANSECT\fP 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 2 3posix 3pm 3perl 3am 5 4 9 6 7", unless overridden by the \fBSECTION\fP directive
in \fI/etc/manpath.config\fP.
.TP 
.if  !'po4a'hide' .BR MANPAGER , " PAGER"
If $\fBMANPAGER\fP or $\fBPAGER\fP is set ($\fBMANPAGER\fP is used in preference),
its value is used as the name of the program used to display the manual
page.  By default, \fBpager\fP is used, falling back to \fBcat\fP if
\fBpager\fP is not found or is not executable.

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.
.TP 
.if  !'po4a'hide' .B MANLESS
If $\fBMANLESS\fP is set, its value will be used as the default prompt string
for the \fBless\fP pager, as if it had been passed using the \fB\-r\fP option (so
any occurrences of the text \fB$MAN_PN\fP will be expanded in the same way).
For example, if you want to set the prompt string unconditionally to \(lqmy
prompt string\(rq, set $\fBMANLESS\fP to \(oq\fB\-Psmy\ prompt\ string\fP\(cq.
Using the \fB\-r\fP option overrides this environment variable.
.TP 
.if  !'po4a'hide' .B BROWSER
If $\fBBROWSER\fP 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 \fBman\fP
\fB\-\-html\fP.  In each command, \fI%s\fP is replaced by a filename containing the
HTML output from \fBgroff\fP, \fI%%\fP is replaced by a single percent sign (%),
and \fI%c\fP is replaced by a colon (:).
.TP 
.if  !'po4a'hide' .B SYSTEM
Hvis $\fBSYSTEM\fP er angivet, vil det have den samme effekt, som hvis den var
blevet angivet som argument for tilvalget \fB\-m\fP.
.TP 
.if  !'po4a'hide' .B MANOPT
If $\fBMANOPT\fP is set, it will be parsed prior to \fBman's\fP command line and
is expected to be in a similar format.  As all of the other \fBman\fP
specific environment variables can be expressed as command line options, and
are thus candidates for being included in $\fBMANOPT\fP 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.
.TP 
.if  !'po4a'hide' .B MANWIDTH
If $\fBMANWIDTH\fP 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 $\fBCOLUMNS\fP, an \fBioctl\fP(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.
.TP 
.if  !'po4a'hide' .B 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 $\fBMAN_KEEP_FORMATTING\fP is
set to any non\-empty value, these formatting characters are retained.  This
may be useful for wrappers around \fBman\fP that can interpret formatting
characters.
.TP 
.if  !'po4a'hide' .B 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 \fBgroff\fP 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 $\fBMAN_KEEP_STDERR\fP is set to any
non\-empty value, error output will be displayed as usual.
