man er systemets manuelle tekstviser. Hver
side-parameter sendt til man er normalt navnet på et
program, et redskab eller en funktion. manualsiden associeret med
hvert af disse parametre findes så og vises. afsnit, hvis
angivet, vil dirigere %man til kun at kigge i det afsnit af
manualen. Standardhandlingen er at søge i alle de tilgængelige
afsnit, 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 SECTION i
/etc/manpath.config), og at vise kun den første side
fundet, selv hvis side findes i flere afsnit.
Tabellen nedenfor viser section-antallet af manualen
efterfulgt af typen af sider de indeholder.

En manualside består af flere afsnit.
Konventionelle afsnitsnavne inkluderer NAVN,
SYNOPSIS, KONFIGURATION, BESKRIVELSE, TILVALG,
AFSLUT-STATUS, RETURVÆRDI, FEJL,
MILJØ, FILER, VERSIONER, KONFORMERER
TIL, NOTER, FEJL, EKSEMPEL, FORFATTERE,
og SE OGSÅ.
De følgende konventioner gælder for afsnittet
SYNOPSIS og kan bruges som en vejledning i andre afsnit.
fed tekst |
skriv præcis som vist. |
kursiv |
erstat med passende argument. |
[-abc] |
et eller alle argumenter inden i [ ] er valgfrie. |
-a|-b |
tilvalg afgrænset af | kan ikke bruges sammen. |
argument ... |
argument kan gentages. |
[udtryk] ... |
hele udtrykket indenfor [ ] kan gentages. |
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 SYNOPSIS section of
this manual page.
- man ls
- Vis manualsiden for punkt (program) ls.
- man
man.7
- Vis manualsiden for makropakken man fra afsnit 7.
- man -a intro
- Vis, i rækkefølge, alle de tilgængelige
intro-manualsider indeholdt i denne manual. Det er muligt at
afbryde mellem successive visninger eller udelade nogle af dem.
- 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
- Søg i de korte beskrivelser og navnene på manualsiderne for
nøgleordet printf som regulært udtryk. Udskriv
resultaterne. Svarer til apropos printf.
- man -f smail
- Slå manualsiderne refereret af smail op og vis den korte
beskrivelse for det fundne resultat. Svarer til
whatis smail.
Mange tilvalg er tilgængelige for man 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 man. Det er muligt at angive variablen
»catch all« $MANOPT 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). man vil fortolke $MANOPT 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
$MANOPT, -D kan specificeres som opstartsindstilling for
kommandolinjen. Dette vil tillade man at »glemme« tilvalgene
specificeret i $MANOPT selvom de stadig må have været
gyldige..
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.
Oversættelser er tilgængelige via denne pakke.
Oversatte manualsider kan tilgås (hvis de er tilgængelige
på dit system) via brug af sprog-funktioner. For at aktivere
denne understøttelse, er det nødvendigt at angive enten
$LC_MESSAGES, $LANG eller en anden systemafhængig
miljøvariabel for dit sprog, normalt specificeret i det POSIX
1003.1-baserede format:
<language>[_<territory>[.<tegnsæt>[,<version>]]]
Hvis den ønskede side er tilgængelig i dit
sprog, 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.
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.
Filtrene tydes vis et antal metoder. Først tydes
kommandolinjetilvalget -p eller miljøvariablen
$MANROFFSEQ. Hvis -p 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
'\" <string>
Hvor streng kan være enhver kombination af bogstaver
beskrevet af tilvalget -p 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 (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.
Tilvalg uden argumenter som dublikeres enten på
kommandolinjen, i $MANOPT, eller begge, er ikke skadelige. For
tilvalg som kræver et argument, vil hver dublikering
tilsidesætte den tidligere argumentværdi.
- -C fil, --config-file=fil
- Brug denne brugerkonfigurationsfil frem for standarden
~/.manpath.
- -d, --debug
- Vis fejlsøgningsinformation.
- -D, --default
- Dette tilvalg udstedes normalt som det første tilvalg og nulstiller
man's opførsel til standarden. Dets brug er at nulstille
disse tilvalg, som måske er angivet i $MANOPT. Ethvert
tilvalg som følger -D vil have deres normale effekt.
- --warnings[=advarsler]
- Aktiver advarsler fra groff. Dette kan gøres for at
udføre sanitetskontrol på kildetekst for manualsider.
advarsler er en kommaadskilt liste med advarselsnavne; hvis den
ikke er angivet, er standarden »mac«. Se
“Warnings” node i info groff for en liste over
tilgængelige advarselsnavne.
- -f, --whatis
- Svarer til whatis. Vis en kort beskrivelse fra manualsiden, hvis
tilgængelig. Se whatis(1) for detaljer.
- -k, --apropos
- Svarer til apropos. Søg i de korte manualsidebeskrivelser
for nøgleord og vis alle match. Se apropos(1) for
detaljer.
- -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
- Vis ikke reelt manualsiden, men vis placeringerne for nroff-kildefilerne,
som ville blive formateret.
- -W, --where-cat,
--location-cat
- Vis ikke reelt manualsiderne, men vis dog placeringerne for
katalogfilerne, som ville være blevet vist. Hvis -w og -W begge er
angivet, så vis begge adskilt af mellemrum.
- -c, --catman
- Dette tilvalg er ikke for generel brug og bør kun bruges af
programmet catman.
- -R kodning, --recode=kodning
- 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.
- -L sprog, --locale=sprog
- man vil normalt bestemme dit lokale sprog med et kald til
C-funktionen setlocale(3), som undersøger diverse
miljøvariabler, muligvis inklusive $LC_MESSAGES og
$LANG. For midlertidigt at overskrive den afslørede
værdi bruges dette tilvalg til at supplere en sprog-streng
direkte til man. 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.
-m system[,...],
--systems=system[,...]
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
-m NytOS.
Det angivet system kan være en kombination af
kommaadskilt operativsystemnavne. For at inkludere en søgning i
manualsiderne for udgangspunktets operativsystem inkluderes systemnavnet
man i argumentstrengen. Dette tilvalg vil overskrive
miljøvariablen $SYSTEM.
- -M sti, --manpath=sti
- Angiv en alternativ manualsti. Som standard bruger man
manpath-afledt kode til at bestemme søgestien. Dette tilvalg
overskriver miljøvariablen $MANPATH og medfører at
tilvalget -m 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 -l option.
- -S liste, -s liste, --sections=liste
- 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
- Hvis enten tilvalget --regex eller --wildcard bruges, match
kun sidenavne, ikke sidebeskrivelser, som med whatis(1). Ellers,
ingen effekt.
- -a, --all
- Som standard vil man afslutte efter visning af den mest egnet
manualside den finder. Brug af dette tilvalg tvinger man til at
vise alle manualsiderne med navne som matcher søgekriteriet.
- -u, --update
- Dette tilvalg får man til at udføre en »inode
level«-konsistenskontrol på dets databasemellemlager for at
sikre at de er en præcis repræsentation af filsystemet. Det
vil kun have en nyttig effekt hvis man er installeret med
setuid-bitsættet.
- --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
For at deaktivere denne opførsel så brug
tilvalget --no-subpages.
$ 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
- -P tekstviser, --pager=tekstviser
- Specify which output pager to use. By default, man uses
pager, falling back to cat if pager is not found or
is not executable. 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
- Hvis en nylig version af less bruges som tekstsøger,
så vil man forsøge at angive den på sin prompt
og vælge nogle fornuftige tilvalg. Standardprompten ser
således ud
Manualside navn(sec) line x
hvor navn benvæner manualsidenavnet,
sektion benævner sektionen den blev fundet under og
x det nuværende linjenummer. Dette opnås ved at
bruge miljøvariablen $LESS.
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\\%..
(tryk h for hjælp eller q for afslut)
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.

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 kodning, --encoding=kodning
- 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 streng, --preprocessor=streng
- 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
- Brug groff -mandoc til at formatere manualsiden til standardud.
Tilvalget er ikke krævet sammen med -H, -T eller
-Z.
- -T[enhed],
--troff-device[=enhed]
- Denne indstilling bruges til at ændre groff-resultater
(eller muligvis troff'er), så de er egnet for en enhed
udover standarden. -t er underforstået. Eksempler (indeholdt
med Groff-1.17) inkluderer dvi, latin1, ps,
utf8, X75 og 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 vil køre troff og så bruge en passende
efterbrænder til at fremstille et resultat egnet for den valgte
enhed. Hvis groff -mandoc er groff, så vil dette
tilvalg sendes til groff og vil undertrykke brugen af en
efterbrænder. -t er underforstået.
- -?, --help
- Vis en hjælpebesked og afslut.
- --usage
- Vis en kort hjælpebesked og afslut.
- -V, --version
- Vis versionsinformation.
- 0
- Programkørsel endt uden fejl.
- 1
- Brugs-, syntaks- eller konfigurationsfilfejl.
- 2
- Operationel fejl.
- 3
- En underproces returnerede en afslutningsstatus forskellig fra nul.
- 16
- Mindst en af siderne/filerne/nøgleordene fandtes ikke eller blev
ikke matchet.
- 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 2 3posix 3pm 3perl 3am 5 4 9 6
7", unless overridden by the SECTION directive in
/etc/manpath.config.
- 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, pager is used, falling back to
cat if pager 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.
- 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
- Hvis $SYSTEM er angivet, vil det have den samme effekt, som hvis
den var blevet angivet som argument for tilvalget -m.
- 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
- Afhængig af system og implementering, vil enten en af eller begge
$LANG og $LC_MESSAGES blive spurgt for den aktuelle beskeds
sprog. man vil vise dets beskeder i det sprog (hvis
tilgængeligt). Se setlocale(3) for mere udførlige
detaljer.
