Generelle tilvalg¶

-C fil, --config-file=fil

Use this user configuration file rather than the default of ~/.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]

Enable warnings from groff. This may be used to perform sanity checks on the source text of manual pages. warnings is a comma-separated list of warning names; if it is not supplied, the default is "mac". To disable a groff warning, prefix it with "!": for example, --warnings=mac,!break enables warnings in the "mac" category and disables warnings in the "break" category. See the “Warnings” node in info groff for a list of available warning names.

Hovedtilstande for operation¶

-f, --whatis

Approximately equivalent to whatis. Display a short description from the manual page, if available. See whatis(1) for details.

-k, --apropos

Approximately equivalent to apropos. Search the short manual page descriptions for keywords and display any matches. See apropos(1) for details.

-K, --global-apropos

Search for text in all manual pages. This is a brute-force search, and is likely to take some time; if you can, you should specify a section to reduce the number of pages that need to be searched. Search terms may be simple strings (the default), or regular expressions if the --regex option is used.

Note that this searches the sources of the manual pages, not the rendered text, and so may include false positives due to things like comments in source files, or false negatives due to things like hyphens being written as "\-" 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.

If this option is not used, then man will also fall back to interpreting manual page arguments as local file names if the argument contains a "/" character, since that is a good indication that the argument refers to a path on the file system.

-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 less, falling back to cat if less 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.

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]

This option is used to change groff (or possibly troff's) output to be suitable for a device other than the default. It implies -t. Examples (as of groff 1.23.0) include dvi, latin1, pdf, ps, utf8, X75 and X100.

-H[browser], --html[=browser]

This option will cause groff to produce HTML output, and will display that output in a web browser. The choice of browser is determined by the optional browser argument if one is provided, by the $BROWSER environment variable, or by a compile-time default if that is unset (usually lynx). This option implies -t, and will only work with GNU troff.

-X[dpi], --gxditview[=dpi]

This option displays the output of groff in a graphical window using the gxditview program. The dpi (dots per inch) may be 75, 75-12, 100, or 100-12, defaulting to 75; the -12 variants use a 12-point base font. This option implies -T with the X75, X75-12, X100, or X100-12 device respectively.

-Z, --ditroff

groff 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.
