       man - an interface to the system reference manuals

SYNOPSIS

       man [man options] [[section] page ...] ...
       man -k [apropos options] regexp ...
       man -K [man options] [section] term ...
       man -k [apropos tilvalg] regexp ...
       man -l [man options] file ...
       man -w|-W [man options] page ...

BESKRIVELSE

       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 (see DEFAULTS), and to show only the first page found, even
       if page exists in several sections.

       Tabellen nedenfor viser section-antallet af manualen  efterfulgt  af  typen  af  sider  de
       indeholder.

       1   Kørbare programmer eller skalkommandoer
       2   Systemkald (funktioner stillet til rådighed af kernen)
       3   Bibliotekskald (funktioner i programbiblioteker)
       4   Specielle filer (normalt fundet i /dev)
       5   File formats and conventions, e.g. /etc/passwd
       6   Spil
       7   Diverse (inklusive makropakker og konventioner), f.eks. man(7), groff(7)
       8   Kommandoer til systemadministration (normalt kun for root)
       9   Kernerutiner [Ikkestandard]

       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.

EKSEMPLER

       man ls
           Vis manualsiden for punkt (program) ls.

       man man.7
           Display the manual page for macro package man from section 7.  (This is an alternative
           spelling of "man 7 man".)

       man 'man(7)'
           Display  the  manual  page  for  macro  package  man from section 7.  (This is another
           alternative spelling of "man 7 man".  It may  be  more  convenient  when  copying  and
           pasting  cross-references to manual pages.  Note that the parentheses must normally be
           quoted to protect them from the shell.)

       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 bash | lpr -Pps
           Format  the manual page for bash 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.

OVERBLIK

       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.

       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.

       Manual  pages  are  normally  stored  in  nroff(1)   format  under  a  directory  such  as
       /usr/share/man.   In  some  installations,  there  may  also  be preformatted cat pages to
       improve performance.  See manpath(5)  for details of where these files are stored.

       This package supports manual pages in multiple languages, controlled by your  locale.   If
       your  system  did  not  set  this  up  for  you  automatically,  then  you may need to set
       $LC_MESSAGES, $LANG, or another system-dependent environment  variable  to  indicate  your
       preferred locale, usually specified in the POSIX 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).

       If you find that the translations 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.

       Individual manual pages are normally written and maintained  by  the  maintainers  of  the
       program,  function,  or  other  topic  that  they document, and are not included with this
       package.  If you find that a manual page is missing or inadequate, please report  that  to
       the maintainers of the package in question.

       For information om andre funktioner og udvidelser tilgængelige med denne manualtekstviser,
       så læs venligst dokumenterne leveret med denne pakke.

STANDARDER

       The order of sections to search may be overridden by the environment variable $MANSECT  or
       by the SECTION directive in /etc/manpath.config.  By default it is as follows:

              1 n l 8 3 2 3posix 3pm 3perl 3am 5 4 9 6 7

       The  formatted  manual page is displayed using a pager.  This can be specified in a number
       of ways, or else will fall back to a default (see option -P for details).

       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

       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.

   Generelle tilvalg
       -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.

   Hovedtilstande for operation
       -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
              Don't  actually  display  the  manual page, but do print the location of the source
              nroff file that would be formatted.  If the -a option is also used, then print  the
              locations of all source files that match the search criteria.

       -W, --where-cat, --location-cat
              Don't  actually  display  the  manual  page,  but  do  print  the  location  of the
              preformatted cat file that would be displayed.  If the -a option is also used, then
              print the locations of all preformatted cat files that match the search criteria.

              If -w and -W are both used, then print both source file and cat file separated by a
              space.  If all of -w, -W, and -a are used, then do this for each possible match.

       -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.

              Consider  using  man-recode(1)  instead for converting multiple manual pages, since
              it has an interface designed for bulk conversion and so can be much faster.

   Finde manualsider
       -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 list, -s list, --sections=list
              The given list is a colon- or comma-separated list of sections, used  to  determine
              which  manual  sections  to  search  and  in what order.  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
              This  option  causes  man  to update its database caches of installed manual pages.
              This is only needed in rare situations, and it is normally better to  run  mandb(8)
              instead.

       --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

   Kontrol af formateret resultat
       -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\\%..

              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.

              Beskrivelse           Oktal   latin1   ascii
              ─────────────────────────────────────────────
              continuation hyphen    255      ‐        -
              bullet (middle dot)    267      •        o
              acute accent           264      ´        '
              multiplication sign    327      ×        x

              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.

MILJØ

       MANPATH
              If $MANPATH is set, its value is used as the path to search for manual pages.

       MANROFFOPT
              Every time man invokes the formatter (nroff, troff, or groff), it adds the contents
              of $MANROFFOPT to the formatter's command line.

       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.

       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, 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, and
              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.
