       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   Miscellaneous  (including  macro  packages  and  conventions),  e.g. man(7), groff(7),
           man-pages(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 0 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[,...]
              If this system has access to other operating systems' 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.

              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.

              See the SEARCH PATH section of manpath(5)  for the default behaviour and details of
              how this environment variable is handled.

       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  0  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.

       MAN_DISABLE_SECCOMP
              On  Linux,  man  normally  confines subprocesses that handle untrusted data using a
              seccomp(2)  sandbox.  This  makes  it  safer  to  run  complex  parsing  code  over
              arbitrary  manual  pages.   If  this  goes  wrong  for some reason unrelated to the
              content of the page being  displayed,  you  can  set  $MAN_DISABLE_SECCOMP  to  any
              non-empty value to disable the sandbox.

       PIPELINE_DEBUG
              If  the  $PIPELINE_DEBUG  environment  variable  is set to "1", then man will print
              debugging messages to standard error describing each subprocess it runs.

       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.
