       mandb - create or update the manual page index caches

SAMENVATTING

       mandb [-dqsucpt|-h|-V] [-C file] [manpath]
       mandb [-dqsut] [-C file] -f filename ...

BESCHRIJVING

       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  can  be  compiled  with  support  for  any  one of the following
       database types.

       Name                Type          Async   Filename
       ----------------------------------------------------------
       Berkeley db         Binary tree   Yes     index.bt
       GNU gdbm v >= 1.6   Hashed        Yes     index.db
       GNU gdbm v <  1.6   Hashed        No      index.db
       UNIX ndbm           Hashed        No      index.(dir|pag)

       Those database types that support asynchronous updates provide enhanced
       speed  at  the  cost  of  possible  corruption  in the event of unusual
       termination.  In an unusual case where this has  occurred,  it  may  be
       necessary  to rerun mandb with the -c option to re-create the databases
       from scratch.

OPTIES

       -d, --debug
              Foutinformatie tonen.

       -q, --quiet
              Produce no warnings.

       -s, --no-straycats
              Do not spend time looking  for  or  adding  information  to  the
              databases regarding stray cats.

       -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
              Create   user   databases  only,  even  with  write  permissions
              necessary to create system databases.

       -t, --test
              Perform correctness checks on  manual  pages  in  the  hierarchy
              search  path.   With  this option, mandb will not alter existing
              databases.

       -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 bestand, --config-file=bestand
              Gebruik  dit  gebruikersconfiguratiebestand  in  plaats  van  de
              standaard van ~/.manpath.

       -h, --help
              Show the usage message, then exit.

       -V, --version
              Show the version, then exit.

STOPSTATUS

       0      Programma correct uitgevoerd.

       1      Usage, syntax, or configuration file error.

       2      Uitvoeringsfout.

       3      A child process failed.

DIAGNOSTICS

       The following warning messages can be emitted during database building.

       <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.

       <filename>: genegeerde onzin bestandsnaam
               <filename> kan een al dan niet geldige man-pagina zijn, maar de
              naam  is  ongeldig.   Dit  wordt  meestal  veroorzaakt  door een
              man-pagina met een uitbreiding van de  sectie   <x>  die  in  de
              man-paginasectie <y> is gestopt.

       <filename_mask>: strijdende extensies
              Het jokerteken <filename_mask> is niet uniek.  Dit wordt meestal
              veroorzaakt door het bestaan van zowel  een  gecomprimeerde  als
              een  gedecomprimeerde  versie  van  dezelfde  man-pagina.   Alle
              behalve de meeste recente versie worden genegeerd.

       /var/cache/man/index.(bt|db|dir|pag)

       Oudere locaties van de database-cache bestaan uit:

       /usr/man/index.(bt|db|dir|pag)
              Een traditionele, algemene index-database-cache.

       /var/catman/index.(bt|db|dir|pag)
              An alternate or FSSTND compliant global index database cache.

ZIE OOK

       lexgrog(1), man(1), manpath(5), catman(8)

       De voormalige sectie WAT IS ONTLEDEN is nu onderdeel van lexgrog(1).
