NAVN¶
mandb - create or update the manual page index caches
SYNOPSIS¶
mandb [
-dqsucpt?V] [
-C fil] [
manualsti]
mandb [
-dqsut] [
-C fil]
-f
filnavn ...
BESKRIVELSE¶
mandb is used to initialise or manually update
index database
caches that are usually maintained by
man. The caches contain
information relevant to the current state of the manual page system and the
information stored within them is used by the man-db utilities to enhance
their speed and functionality.
When creating or updating an
index,
mandb will warn of bad ROFF
.so requests, bogus manual page filenames and manual pages from which the
whatis cannot be parsed.
Supplying
mandb with an optional colon-delimited path will override the
internal system manual page hierarchy search path, determined from information
found within the man-db configuration file.
DATABASE CACHES¶
mandb kan kompileres med understøttelse for enhver af de
følgende databasetyper.

De databasetyper som understøtter asynkrone opdateringer tilbyder
forbedret hastighed på bekostning af muligheden for korruption i
tilfælde af usædvanlig afslutning. I et usædvanligt
tilfælde, hvor dette er opstået, kan det være
nødvendigt at genkøre
mandb med tilvalget
-c for
at genskabe databaserne fra bunden af.
TILVALG¶
- -d, --debug
- Vis fejlsøgningsinformation.
- -q, --quiet
- Lav ingen advarsler.
- -s, --no-straycats
- Brug ikke tid på at kigge efter eller tilføje information
til databaserne angående vildfarne katalogsider.
- -p, --no-purge
- Do not spend time checking for deleted manual pages and purging them from
the databases.
- -c, --create
- By default, mandb will try to update any previously created
databases. If a database does not exist, it will create it. This option
forces mandb to delete previous databases and re-create them from
scratch, and implies --no-purge. This may be necessary if a
database becomes corrupt or if a new database storage scheme is introduced
in the future.
- -u, --user-db
- Opret kun brugerdatabaser, selv med skriverettigheder nødvendige
for at oprette systemdatabaser.
- -t, --test
- Udfør kontrol af korrekthed på manualsider i
søgestien for hierarkiet. Med dette tilvalg vil mandb ikke
ændre eksisterende databaser.
- -f, --filename
- Update only the entries for the given filename. This option is not for
general use; it is used internally by man when it has been compiled
with the MAN_DB_UPDATES option and finds that a page is out of
date. It implies -p and disables -c and -s.
- -C fil, --config-file=fil
- Brug denne brugerkonfigurationsfil frem for standarden
~/.manpath.
- -?, --help
- Vis brugsbeskeden, afslut så.
- --usage
- Vis en kort hjælpebesked og afslut.
- -V, --version
- Vis versionen og afslut.
AFSLUT-STATUS¶
- 0
- Programkørsel endt uden fejl.
- 1
- Brugs- syntaks- eller konfigurationsfilfejl.
- 2
- Operationel fejl.
- 3
- En underproces mislykkedes.
DIAGNOSTICS¶
De følgende advarselsbeskeder kan udelades under opbygning af database.
- <filename>: whatis parse for page(sec) failed
- An attempt to extract whatis line(s) from the given <filename>
failed. This is usually due to a poorly written manual page, but if many
such messages are emitted it is likely that the system contains
non-standard manual pages which are incompatible with the man-db whatis
parser. See the WHATIS PARSING section in lexgrog(1) for
more information.
- <filename>: is a dangling symlink
- <filename> does not exist but is referenced by a symbolic link.
Further diagnostics are usually emitted to identify the <filename>
of the offending link.
- <filename>: bad symlink or ROFF `.so' request
- <filename> is either a symbolic link to, or contains a ROFF include
request to, a non existent file.
- <filnavn>: ignorerer falske filnavne
- The <filename> may or may not be a valid manual page but its name is
invalid. This is usually due to a manual page with sectional extension
<x> being put in manual page section <y>.
- <filename_mask>: konkurrerende udvidelser
- Jokertegnet <filename_mask> er ikke unik. Dette skyldes normalt
eksistensen af både en pakket og udpakket version af den samme
manualside. Alle undtagen de seneste ignoreres
FILER¶
- /etc/manpath.config
- konfigurationsfil for man-db.
- /var/cache/man/index.(bt|db|dir|pag)
- Et FHS-overholdende globalt index-databasemellemlager.
Tidligere placeringer for databasens mellemlager inkluderede:
- /usr/man/index.(bt|db|dir|pag)
- Et traditionelt globalt index-databasemellemlager.
- /var/catman/index.(bt|db|dir|pag)
- An alternate or FSSTND compliant global index database cache.
