whatis \- vis beskrivelser på en linje for manualsider
.SH SYNOPSIS
\fBwhatis\fP [\|\fB\-dlv?V\fP\|] [\|\fB\-r\fP\||\|\fB\-w\fP\|] [\|\fB\-s\fP \fIliste\fP\|]
[\|\fB\-m\fP \fIsystem\fP\|[\|,.\|.\|.\|]\|] [\|\fB\-M\fP \fIsti\fP\|] [\|\fB\-L\fP \fIsted\fP\|]
[\|\fB\-C\fP \fIfil\fP\|] \fInavn\fP \&.\|.\|.
.SH BESKRIVELSE
Each manual page has a short description available within it.  \fBwhatis\fP
searches the manual page names and displays the manual page descriptions of
any \fIname\fP matched.

\fIname\fP may contain wildcards (\fB\-w\fP)  or be a regular expression (\fB\-r\fP).
Using these options, it may be necessary to quote the \fIname\fP or escape (\e)
the special characters to stop the shell from interpreting them.

\fBindex\fP databases are used during the search, and are updated by the
\fBmandb\fP program.  Depending on your installation, this may be run by a
periodic cron job, or may need to be run manually after new manual pages
have been installed.  To produce an old style text \fBwhatis\fP database from
the relative \fBindex\fP database, issue the command:

\fBwhatis \-M\fP \fImanpath\fP \fB\-w '*' | sort >\fP \fImanpath/whatis\fP

where \fImanpath\fP is a manual page hierarchy such as \fI/usr/man\fP.
.SH TILVALG
.TP 
.if  !'po4a'hide' .BR \-d ", " \-\-debug
Vis fejlsøgningsinformation.
.TP 
.if  !'po4a'hide' .BR \-v ", " \-\-verbose
Vis uddybende advarsler.
.TP 
.if  !'po4a'hide' .BR \-r ", " \-\-regex
Interpret each \fIname\fP as a regular expression.  If a \fIname\fP matches any
part of a page name, a match will be made.  This option causes \fBwhatis\fP
to be somewhat slower due to the nature of database searches.
.TP 
.if  !'po4a'hide' .BR \-w ", " \-\-wildcard
Interpret each \fIname\fP as a pattern containing shell style wildcards.  For a
match to be made, an expanded \fIname\fP must match the entire page name.  This
option causes \fBwhatis\fP to be somewhat slower due to the nature of
database searches.
.TP 
.if  !'po4a'hide' .BR \-l ", " \-\-long
Tilpas ikke resultatet til terminalbredden. Normalt vil resultatet blive
forkortet til terminalbredden for at undgå grimme resultater fra dårligt
skrevet \fBNAVN\fP\-afsnit.
.TP

.\"
.\" Due to the rather silly limit of 6 args per request in some `native'
.\" *roff compilers, we have do the following to get the two-line
.\" hanging tag on one line. .PP to begin a new paragraph, then the
.\" tag, then .RS (start relative indent), the text, finally .RE
.\" (end relative indent).
.\"
Søg kun i de angivne manualafsnit. \fIliste\fP er en kolon\- eller kommaadskilt
liste af afsnit. Hvis et punkt i \fIliste\fP er et simpelt afsnit, for eksempel
»3«, så vil den viste beskrivelsesliste inkludere sider i afsnit »3«,
»3perl«, »3x« og så videre; mens at hvis et punkt i \fIliste\fP har en
udvidelse, for eksempel »3perl«, så vil listen kun inkludere sider i den
præcise del af manualafsnittet.
.PP
\fB\-m\fP \fIsystem\fP\|[\|,.\|.\|.\|]\|, \fB\-\-systems=\fP\fIsystem\fP\|[\|,.\|.\|.\|]
.RS
If this system has access to other operating system's manual page names,
they can be accessed using this option.  To search NewOS's manual page
names, use the option \fB\-m\fP \fBNewOS\fP.

The \fIsystem\fP specified can be a combination of comma delimited operating
system names.  To include a search of the native operating system's manual
page names, include the system name \fBman\fP in the argument string.  This
option will override the $\fBSYSTEM\fP environment variable.
.RE
.TP 
\fB\-M\ \fP\fIsti\fP,\ \fB\-\-manpath=\fP\fIsti\fP
Specify an alternate set of colon\-delimited manual page hierarchies to
search.  By default, \fBwhatis\fP uses the $\fBMANPATH\fP environment variable,
unless it is empty or unset, in which case it will determine an appropriate
manpath based on your $\fBPATH\fP environment variable.  This option overrides
the contents of $\fBMANPATH\fP.
.TP 
\fB\-L\ \fP\fIsprog\fP,\ \fB\-\-locale=\fP\fIsprog\fP
\fBwhatis\fP vil normalt bestemme dit lokale sprog med et kald til
C\-funktionen \fBsetlocale\fP(3), som undersøger diverse miljøvariabler,
muligvis inklusive $\fBLC_MESSAGES\fP og $\fBLANG\fP. For midlertidigt at
overskrive den afslørede værdi bruges dette tilvalg til at supplere en
\fIsprog\fP\-streng direkte til \fBwhatis\fP. Bemærk at det ikke vil træde i
kraft før søgningen efter sider rent faktisk begynder. Resultatet såsom
hjælpebeskeden vil altid blive vist i det oprindeligt bestemte sprog.
.TP 
\fB\-C\ \fP\fIfil\fP,\ \fB\-\-config\-file=\fP\fIfil\fP
Brug denne brugerkonfigurationsfil frem for standarden \fI~/.manpath\fP.
.TP 
.if  !'po4a'hide' .BR \-? ", " \-\-help
Vis en hjælpebesked og afslut.
.TP 
.if  !'po4a'hide' .BR \-\-usage
Vis en kort hjælpebesked og afslut.
.TP 
.if  !'po4a'hide' .BR \-V ", " \-\-version
Vis versionsinformation.
.SH AFSLUT\-STATUS
.TP 
.if  !'po4a'hide' .B 0
Programkørsel endt uden fejl.
.TP 
.if  !'po4a'hide' .B 1
Brugs\-, syntaks\- eller konfigurationsfilfejl.
.TP 
.if  !'po4a'hide' .B 2
Operationel fejl.
.TP 
.if  !'po4a'hide' .B 16
Intet blev fundet som matchede de angivne kriterier.
.SH MILJØ
.TP 
.if  !'po4a'hide' .B SYSTEM
Hvis $\fBSYSTEM\fP er angivet, vil det have den samme effekt, som hvis den var
blevet angivet som argument for tilvalget \fB\-m\fP.
.TP 
.if  !'po4a'hide' .B MANPATH
If $\fBMANPATH\fP is set, its value is interpreted as the colon\-delimited
manual page hierarchy search path to use.
.TP 
.if  !'po4a'hide' .B MANWIDTH
If $\fBMANWIDTH\fP is set, its value is used as the terminal width (see the
\fB\-\-long\fP option).  If it is not set, the terminal width will be calculated
using the value of $\fBCOLUMNS\fP, an \fBioctl\fP(2)  if available, or falling
back to 80 characters if all else fails.
.SH FILER

.if  !'po4a'hide' .I /usr/share/man/index.(bt|db|dir|pag)
